| 摘 要： | 以枯草芽孢杆菌(Bacillus subtilis)为生物吸附剂,讨论了其对Cu2+的生物吸附规律,并通过酸碱滴定这一表面分析手段,结合相关软件及傅里叶变换红外光谱(FTIR)分析了菌体表面主要的基团种类及数量.结果表明,枯草芽孢杆菌对Cu2+吸附的最佳条件是:pH为6、吸附时间为24 h,菌悬液用量和Cu2+初始浓度...

| Abstract: | The batch removal of Cu2+ from aqueous solution by adsorption on biosorbents Bacillus subtilis was performed to determine the effect of adsorption time,pH,biosorbent dosage and initial Cu2+ concentration on the adsorptive capacity for Cu2+.The acid-base titration and FTIR were employed to analyze the surface properties of Bacillus subtilis.The optimum adsorption conditions were pH of 6 and adsorption time of 24 h;the biosorbent dosage and initial Cu2+ concentration should be chosen according to the practica... |
