AB  - In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was
investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were
grown in laboratory column bioreactors. The biofilms were continuously treated with sterile
synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of
adsorption was studied as function of pH, adsorbent dose and contact time. Efficiency of
mercury ion removal from chlor-alkali industry wastewater by aluminum sulfate and ferric
chloride was also determined. Under acidic condition the adsorption of mercury by cellulose
was quite low and increasing processing time more than 10min has no remarkably effect on the
adsorption rate. Adsorption capacity of cellulose under dynamic condition for chlor-alkali
wastewater was 65µg/g which was less than the value (80µg/g) that obtained from batch adsorption experiments for synthetic wastewater.
