是哪个播种人,走在地上,播下我们内心的火种?种子从他紧握的掌心射出,像彩虹的弧线,落在冻土上,沃土上,热沙上。它们静静地睡在那儿,贪婪的吸着我们的生命,直到把土地轰裂成片片,为了长出这朵你看到的向阳花, 相似文献

A process of biosorption of Cu2 , Zn2 and Cd2 on Bacillus subtilis was investigated. The experiments show that the process of biosorption is quite fast. The maximum adsorption was reached after 5 min and hardly changed with time. The experimental data was analyzed using four sorption kinetic models: the pseudo-first-order, the Ritchie second-order, the modified second-order and the Elovich equations, which helped to determine the best-fit equation for the sorption of metal ions onto biomass. The results show that both the Ritchie second-order and modified second-order equations can fit the experimental data. The Langmuir model is able to accurately describe adsorption of Cu2 and Zn2 on B. subtilis. The experimental data points of adsorption Cd2 and Zn2 on B. subtilis are described by Freundlich isotherms model. 相似文献
