Effect of pH value on electrostatic and specific adsorptions of Cu~(2+) by paddy soils;

pH值对水稻土Cu~(2+)静电吸附与专性吸附的影响

It can be seen that the adsorption of arsenic is a kind of specific adsorption.

由此得出了红土吸附砷属于专性吸附的结论。

The results showed that the values of zeta potential in colloidal suspensions of paddy soils with various Cd/Pb molar ratios can be used to predict the relative strength of specific adsorption of heavy metals on soil surface.

测定了3种水稻土胶体在不同Cd/Pb摩尔比的悬液体系中的Zeta电位,并与2种重金属离子在土壤中的吸附量和解吸量进行比较,当Cd/Pb摩尔比为1∶4时,Zeta电位数值最高;Cd/Pb摩尔比为1∶1时Zeta电位数值居中;Cd/Pb摩尔比为4∶1时Zeta电位数值最小,因此,Pb(Ⅱ)在三种土壤表面发生专性吸附的能力均大于Cd(Ⅱ),这与土壤中Pb(Ⅱ)和Cd(Ⅱ)的吸附量和解吸量的结果相一致。
