摘要：

The efficacy of immobilized Saccharomyces cerevisiae (biomatrix) for the sorption of different metal ions and its potential applications in nuclear waste treatment were investigated. The sorption of radionuclides such as (2)33U, (241A)m, Ce-144, Cs-137 and Sr-90 was studied under different experimental conditions. More than 95% sorption of UO22+, Pu4+, Am3+ and Ce3+ could be obtained in the pH range 1 to 2 of the aqueous solutions. However the sorption of Cs+ and Sr2+ were negligible under the similar experimental conditions. The infrared spectra and scanning electron microscopic images of the control and uranium-bearing biomatrix were studied to understand the chemistry of metal uptake by this biomatrix.
