Biosorption Behavior of U(VI) in Wastewater Containing U(VI) by Immobilized Saccharomyces Cerevisiae

In this study, Immobilized Saccharomyces Cerevisiae (ISC) was prepared through sodium alginate embedding gelatin method after the dry cells had been cross-linked by formaldehyde. The influences of solution pH, initial U(VI) concentration, and contact time on U(VI) biosorption were studied. The optimal U(VI) adsorption conditions was observed at pH 7.0, initial U(VI) concentration 60 mg.L-1, biosorbent dose biosorption equilibrium was established in 1.5h.
