Description Oxidation of ferrous ions using Acidothiobacillus ferrooxidance has an important application in removal of arsenic(As) by chemo-biochemical process.Arsenite (As+3) was found to oxidised to arsenate (As+5) in presence of A. ferrooxidance and ferric (Fe+3) ions. The resulting arsenate can be removed by precipitation and filtration. The aim of present work was to establish the effect of basic parameters namely temperature, pH, initial cell density and Fe+2 concentration on microbial assisted arsenic removal using bio-oxidation of ferrous to ferric at bench scale.
