| 摘 要： | 选用人工合成的两种铁氧化物(针铁矿和赤铁矿)和一种土壤,研究了Zn2 在供试样品上的吸附,并对其吸附机理进行了分析.结果表明,供试样品吸附Zn2 的量随其浓度的升高而增加,土壤、赤铁矿、针铁矿吸附Zn2 的量依次增加;供试样品吸附Zn2 后,溶液的pH值均降低;用线性方程、Langmuir、Freundlich、Dubinin-Redushkerich等温吸附方程对供试样品吸附Zn2 的数据进行了描述与比较,并结合其组成进行了吸附机理探讨.

| Abstract: | Adsorption of Zn2 on goethite,hematite and a red soil was investigated,and the adsorption mechanism was discussed.The results indicated that: the adsorption capacity of Zn2 on tested samples increased with the increase in concentrations of Zn2 .The amount of adsorption of Zn2 on tested samples was in order as followed: red soil
