Introduction:
Activated carbon is a common term for a family of highly porous carbonaceous materials that cannot be defined by a structural formula, or by chemical analysis. In other words, a piece of carbon with millions of tiny interlocking holes (called pores) is called activated carbon. Activated carbon is essentially carbon, it is inert, and so it carries no charge. Since activated carbon carries no charge, its internal surface area is also neutral, therefore activated carbon will adsorb only neutral species. …

Introduction:
Fire assaying is an age-old technique which uses intense heat and dry reagents called fluxes to extract precious metals for its ores. Nowadays, lead fire assay and nickel sulfide fire assay are widely applied as separation and pre-concentration procedures for gold and the platinum-group elements before instrumental determination. For the analysis of all platinum group elements (PGE) in geological samples, the best method for sample decomposition and precious metals extraction is nickel sulfide fire as…

NPK fertilizers are a class of complex fertilizers that contain the elements nitrogen, phosphorous and potassium.
Nitrogen is used by the plants to provide leafy growth and formation of stems and branches. Basically, the more leaf a plant produces, the higher is its nitrogen requirement.
Phosphorous is essential for seed germination and root development. It is useful particularly for young plants forming their root system and by food and seed crops. Root vegetables such as carrots and turnips need plentiful phosphorous to…

Introduction
Portland cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials like sand or gravels to bind them together. It is a backbone material for any kind of masonry construction works like household foundations, multistoried building, roads, bridge construction etc. So quality checking of cement either in factory site or in laboratory is a necessary action to ascertain its strength. Key ingredient of this cement is clinker which is a h…

A brief discussion on Lead acid battery recycling and associated challenges
Lead acid batteries (LAB) are easy to design, low cost in manufacturing, safe and reliable. Most of the lead produced world wide are consumed by the LAB industry. Unfortunately, lead is a hazardous material and essentially needs to be recycled to minimize the impact on the environment. Almost 90% of the LABs produced globally are recycled today.
A spent lead battery has four components that can be recycled. Approxim…

Introduction
Phosphorus is a hazardous impurity (poison) in steel. Steel with high phosphorus content becomes extremely brittle at a low temperature, and the mechanical properties of steel exhibit worsening impact strength and elongation abruptly decrease. Therefore, for obtaining low-phosphorous manganese-containing steels, it is necessary to have manganese ferroalloys with the lowest possible phosphorus content. The production of such manganese ferroalloys is possible in the presence of low-phosphorus ores and co…

Keywords: Hydrocarbon, Solid Phase Extraction, Paraffin, Gas Chromatography.
Introduction
A simple, fast gas chromatographic-flame ionization detection (GC/FID) method combined with a solid phase extraction (SPE) has been established to determine the mineral oil-saturated hydrocarbons (MOSH) in vegetable oils.
Mineral oils are certain fractions from petroleum refining and maybe traded under various designations such as Paraffinum Liquidum, Paraffin, Petrolatum (soft paraffi…

Abstract:
Alpha-amylase is considered to be one of the primary enzymes responsible for starch degradation in cereals. During grain germination, α-amylase initiates the conversion of starch into simple sugars to fuel embryo and coleoptile growth in the first few days of germination. The present study involves the estimation of Alpha amylase content in four different grains varieties, namely, black matpe, green mung beans, chana and chick peas up to 8 days after germination. It was observed that, alpha amylase …

Introduction
β – Carotene the precursor of Vitamin A is a red-orange pigment present in plants and fruits like carrot, broccoli, lettuce, sweet potato, tomato, and winter squash and gives them their color. More intense the color the more beta carotene it has. This Carotenoid is added to many foods such as margarine, infant formula etc. Carotenoids belong to the most important group of natural pigments as they contribute too many diverse functions due to their high structural diversity. They also possess …

The bursting of crackers during in any occasion increases the concentration of dust and pollutants. The fine dust that settles after bursting crackers is rich in pollutants like oxides of Sulphur and nitrogen, metal dust and organic pollutants.
Even the tiny sparklers, torches and flower pots which are otherwise considered to create no noise at all but can generate thick smoke that can affect the respiratory tract of human. The suspended particulate matter (SPM) levels rise significantly dur…

Abstract:
Anthocyanins are a type of pigment found in fruits that offer health benefit. It belongs to a class of compound called flavonoids that have antioxidant properties. The colour change from pink red to blue violet with change in pH values from 1.0 to 4.5 indicates the presence of anthocyanin. The total anthocyanin content was analyzed by the pH differential method by measuring the absorbance at pH 1.0 and pH 4.5 by UV-Vis spectrophotometer. Anthocyanin content was estimated in five popular fresh fruit sample…

ABSTRACT
Black pepper (Piper nigrum) is a spice vine crop which is used as a food preservative and as an essential component in traditional medicines. Piperine, a major alkaloid, is the major bio-active component of pepper, which imparts pungency and biting taste to it. This naturally occurring alkaloid has numerous demonstrated health effects and beneficial therapeutic properties. Piperine is considered as one of the most promising bioenhancers till date. Several methods used for its extraction and isolation suffe…

Abstract:
The process of repeated frying of refined palm oil plays a significant role in the generation of free radicals, which could be detrimental to human health. In the present study, palm oil was subjected to frying till 8hr and samples were taken at 0hr, 2hr, 4hr, 6hr and 8hr and subjected to physico-chemical analyses including Malondialdehyde (MDA) expressed as Thiobarbituric Acid Reactive Substances (TBARS).It was observed that there were significant increases in free fatty acid (FFA), peroxide value, p-ani…

ABSTRACT:
Determination of Nitrate Nitrogen, Urea –Nitrogen and Ammoniacal Nitrogen in fertilizer samples by IR spectroscopy. The main forms of Nitrogen in fertilizer are Ammoniacal Nitrogen, Urea Nitrogen and Nitrate Nitrogen. In this study, FTIR –ATR spectra of Nitrate, Urea and Ammoniacal Nitrogen standard solution with low to high concentration were prepared by using Potassium Bromide (KBr). The result showed that the wavenumber of Nitrate –Nitrogen (at a region 824 cm-1) Urea- Nit…

The protein digestibility-corrected amino acid score (PDCAAS) has been used to evaluate protein quality in human foods. Previously Amino Acid Scoring (AAS) provides a way to predict how efficiently protein will meet a person’s amino acid needs. But this method has some drawbacks, in this method AAS is determined after acid hydrolysis of proteins which results in total amino acid content but some of the amino acids in the total pool are not bioavailable. Some of the protein may not be dig…

Introduction:
Total carbon in the Biomass is comprised of two fractions: combustible and carbonate carbon. Combustible carbon corresponds to total organic carbon (TOC) while carbonate carbon corresponds to total inorganic carbon. The amount of the combustible carbon content in biomass can be used for the determination of the performance and efficiency of biomass boiler furnaces as well as of different thermo-chemical (liquefaction, gasification, and pyrolysis) reactors for carbonaceous fuels.

Abstract:
This present work was aimed at the quantitative determination of three anti-nutritional factors (Oxalate, Phytate, and polyphenolics) in wine samples. The determination of polyphenolics was done using Folin-Ciocaltau’s Spectrophotometric method; the determination of oxalate was done through titrimetric method and phytate was estimated by spectrophotometric method. The result revealed that the wine samples actually contained these anti-nutritional factors in varying amounts. Intake of the wine over …
