Abstract
Kinetic and Adsorption Study for Removal of Arsenic from Aqueous Medium by Low Cost Bentonite of Rajmahal Hills and Hazaribagh, Jharkhand
Highlights
Arsenic contamination of drinking water has become a matter of worldwide concern
The bentonite minerals were collected from the different sampling sites of Hazaribagh districts mainly located at lat. 23.99°N and long. 85.37°E
All the glassware were washed with dilute acid and washed with double distilled water. 100 mL 2 ppm solution was taken in 250 mL conical flask and 1 g bentonite sample was added to the conical flask and suspension was shaken in a mechanical shaker up to a different interval of time
Summary
Arsenic contamination of drinking water has become a matter of worldwide concern. The danger of arsenic contaminating the water reserves in the entire world is on the rise. Arsenic occurs as arsenic sulphide minerals like arsenopyrites (Jha 2016, Jha 2018). In oxidizing soils arsenate is bound to ferric hydroxide minerals such as ferrihydrite and haematite (Mermut 1994, Brindley 1980). Organic matter converts ferric to more soluble ferrous, in effect dissolving arsenic and causing an increase in arsenic in ground level. Herbicides, industrial and agricultural pollution increases the arsenic level in groundwater (Jha et al 2011, Jha et al 2010). Inorganic arsenicals are more toxic than organic arsenicals. As(III) is more toxic than As(V) ( Jha & Mishra 2012, Lagaly 1995)
