In this experiment, the biosorption of 241Am from solution by Candida sp., and the effects of various experimental conditions on the adsorption were investigated. The preliminary results showed that the adsorption of 241Am by Candida sp. was efficient. 241Am could be removed by Candida sp. of 0.82g/L (dry weight) from 241Am solutions of 5.6-111MBq/L (44.3-877.2μg/L)(C0), with maximum adsorption rate (R) of 98 and maximum adsorption capacities (W) of 63.5MBq/g biomass (dry weight) (501.8μg/g). The biosorption equilibrium was achieved within 4 hour and the optimum pH was pH=2. No significant differences on 241Am adsorption were observed at 10°C-45°C, or in solutions containing Au3+ or Ag+, even 1500 times or 4500 times above the 241Am concentration, respectively. The relationship between concentrations and adsorption capacities of 241Am indicated the biosorption process should be described by a Langmuir adsorption isotherm. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Luo Shunzhong aut Liu Ning aut Yang Yuanyou aut Zhang Taiming aut Jin Jiannan aut Liao Jiali aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/6/2003(2003-06-01), 315-318 0033-8230 91:6/2003<315 2003 91 ract https://doi.org/10.1524/ract.91.6.315.20024 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.91.6.315.20024 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Luo Shunzhong aut NATIONALLICENCE 700 1- Liu Ning aut NATIONALLICENCE 700 1- Yang Yuanyou aut NATIONALLICENCE 700 1- Zhang Taiming aut NATIONALLICENCE 700 1- Jin Jiannan aut NATIONALLICENCE 700 1- Liao Jiali aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/6/2003(2003-06-01), 315-318 0033-8230 91:6/2003<315 2003 91 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
