| 摘 要： | 研究了遵义红土吸附砷对其动电电位的影响 ,从砷酸根浓度和体系pH对红土动电电位影响的角度作了探讨 ,结果表明 ,砷酸根离子浓度越大 ,Zata电位下降幅度越大 ,Zata电位也越低 ;随着体系pH的升高 ,氧化铁胶体动电电位逐渐下降 ,甚至改变了表面电位的符号。由此得出了红土吸附砷属于专性吸附的结论。

| Abstract: | In this paper, the effects of adsorption of arsenic on Zata of red soil were studied. Both the concentration of arsenic and the pH value were examined. Results shown that, with the increase of the concentration of arsenic, the Zata of red soil declined, the Zata of red soil decreased with the increase of the pH value, and even the charge of Zata of red soil was also changed between positive and negative charges. It can be seen that the adsorption of arsenic is a kind of specific adsorption. |
