| 摘 要： | 将改性高粱秸秆用于磷酸根的吸附,研究了时间、酸度、温度以及改性高粱秸秆用量等因素对其吸附性能的影响。结果表明,在常温下,改性高粱秸秆对磷酸根具有良好的吸附性能,吸附时间快。改性高粱秸秆对磷酸根的吸附符合Langmuir和Freundli-ch吸附等温方程及准二级动力学方程,吸附过程以单分子层物理吸附为主。

| Abstract: | Modified sorghum stalk was applied to the adsorption of phosphate,and the effects of various experimental parameters such as pH,absorption time,temperature and the amount of modified sorghum stalk on the absorption were explored.The results showed that,at room temperature,the modified sorghum stalk had a good adsorption behavior to phosphate in short absorption time.The adsorption behaviors of modified sorghum stalk to phosphate accord with Freundlich and Langmuir adsorption isotherms equation,and also meet the pseudo-second-order kinetic equation.The adsorption process mainly relies on monomolecular physical adsorption. |
