Efficiency removing arsenic from drinking water using Aluminium oxide and Ferric Oxide

Abstract

In recent years there has been widespread coverage in the media about the problems caused by arsenic in drinking water. Arsenic contamination in ground water in West Bengal, India, and neighboring Bangladesh has emerged into an international crisis. Over 100 million people are at risk of arsenic poisoning. More recently, because of the recognition that arsenic at low concentrations in drinking water causes severe health effects, extensive research has been carried out to remove arsenic from drinking water. he purpose of this research is to reduce the arsenic level below 10ug/L in drinking water using Aluminum oxide and Ferric oxide. In this study batch adsorption tests were used to evaluate the effects of arsenic adsorption using five ratios of aluminum oxide and ferric oxide. More than 50% of arsenic adsorption efficiency can be achieved by adding (70-100) g/L of total aluminum oxide and ferric oxide in concentrations from 2ppb to 10ppb arsenic.
