dc.description.abstract[中文文摘]从不同来源的细菌菌株中筛选获得一株吸附Pd2 +能力较强的菌株R0 8,经鉴定为地衣芽孢杆菌 (Bacilluslicheniformis)R0 8。R0 8死菌体吸附Pd2 +的最适 pH值为 3 5,其吸附作用是一种快速而非依赖温度的过程。吸附作用受菌体浓度和Pd2 +浓度影响。在起始Pd2 +浓度 2 0 0mg/L、菌浓度 0 4g/L、pH3 5和 30℃条件下 ,吸附 45min ,吸附量为2 2 4 8mg/ g。透射电镜观察显示 ,R0 8死菌体能够还原Pd2 +成Pd0 颗粒。红外光谱分析表明 ,细胞壁上的 COO- 和HPO42 - 基团可能与Pd2 +的生物吸附有关。[英文文摘]The st rain R08, showed relat ively st rong abilit y of adsorbing Pd2+ , was screened from different source of bacterial st rains. T he strain R08 was ident ified as Bacillus lichenif ormis. T he optimum pH value of Pd2+ biosorpt ion by R08 dead biomass is 3. 5. T he biosorption is a rapid and non-temperature dependent process. T he biomass and Pd2+ init ial concentration in solution affected the biosorption process. T he bosorptive capacity could reach 224. 8 mg/ g under the condit ions of Pd2+ 200 mg/ L, 0. 4g biomass/ L , pH3. 5 and 30 e for 45min. TEM observation showed that R08 biomass is able to adsorb and reduce Pd2+ ions to Pd0 particles. IR spect rum analysis indicat ed that COO- and HPO2-4 groups on the cell walls may involve in process of adsorbing Pd2+ .zh_CN
