| 摘 要： | 研究了天然膨润土对醋酸锌溶液中Fe^3 的吸附作用。结果表明：天然膨润土对Fe^3 吸附性能较强，当Fe^3 的浓度为l00mg／L左右时，用膨润土一次性吸附后，溶液中的Fe^3 浓度就可达到Q／HG3-180-77标准规定的要求。吸附受溶液pH、吸附剂用量以及振荡时间的影响，并且溶液中存在的醋酸和醋酸锌会降低膨润土对Fe^3 的吸附容量。

| Abstract: | The adsorption function of Fe 3+ in zinc acetate solution by bentonite was investigated.The results show that the bentonite has good adsorption capacity.When Fe 3+ concentration is about 100 mg/L,the Fe 3+ concentration in zinc acetate can meet the requirement stipulated in the standard of Q/HG3-180-77 after one time adsorption.The adsorption was affected by the pH of solution,amount of adsorbent and contact time.In addition,the acetic acid and zinc acetate in the solution can decrease the adsorption capacity of Fe 3+. |
