REMOVAL OF ARSENIC FROM WATER USING HYBRID MATERIAL

Abstract

Contamination due to heavy metals in water has caused a major concern. It is not only confined to our country, but it is also a serious concern globally. One of among such heavy metals is Arsenic, which is most commonly found in water, especially sub-surface water. The various routes through which these heavy metals can interact with living beings is through water and air. Hence removal of heavy metals is a big necessity for us. In this study, physical methods are used for removal of arsenic. Basically, adsorption technique with Hybrid materials is used. Water sample is prepared by using salt of sodium arsenate. Batch studies were conducted to conclude the optimum pH, optimum concentration and optimum period of hydrolysis. To detect the amount of arsenic, a special instrument called Atomic Absorption Spectrometer (AAS) is used. pH is the measure of acidity or alkalinity of aqueous samples which is measured using pH meter. Hydrolysis can be defined as a phenomenon in which chemical breakdown of a compound occurs with the help of reaction with water.
