The effect of pH and biomass concentration on lead (Pb) adsorption by Saccharomyces cerevisiae from simulated waste water
The contamination of wastewaters, river sediments and soil with toxic metals, is a complex problem. The removal of these contaminations has received much attention in recent years using conventional methods such as chemical reduction, ion exchange, and electrochemical treatment. The alternative meth...

The contamination of wastewaters, river sediments and soil with toxic metals, is a complex problem.

The alternative method is discovered which is biosorption, refers to a physic-chemical binding of metal ions to biomass. The biosorption rate largely depends on parameters such as pH, initial biomass concentration and temperature. The biosorption of lead (Pb2+) from simulated waste water using baker’s yeast biomass is investigated. In this study, biosorption process was carried out in a shake flask at different initial pH and biomass concerntration.
