Abstract

Pellets of Saccharomyces cerevisiae, cross-linked by 13% (w/v) formaldehyde, were used in fixed-bed columns to remove Cr(VI) from electroplating rinse effluent at varied influent pHs (2.5–7.5). The Cr uptake at 60% saturation of the biomass was 6.3 mg/g at an optimum pH of 2.5. Desorption of the bound metal was partially achieved by washing the column biomass with a combined solution of 1% (w/v) formaldehyde and 1 M HNO3. © Rapid Science Ltd. 1998
