| 摘 要： | 研究了在稀溶液中利用十二烷基硫酸钠(NaLS)做活性剂,三氯化铁(FeCl_3·6H_2O)做凝聚剂,通过泡沫分离的方法除去溶液中的重金属离子——铜。探讨了影响分离效率的各种因素——主体溶液中铜离子浓度、活性剂浓度、凝聚剂浓度、气流速度等。以便由此找到通过泡沫分离方法除去铜离子,并使塔底排放液中铜离子含量达到国家排放标准的适宜条件。排放液中铜离子含量用原子吸收分光光度计测定。

| Abstract: | The removal of the heavy metal (copper). ion from dilute aqueous solution by foam fractionation was studied, and sodium dodecyl sulfate t was used as surfactant (NaLS) and ferric chorilide (Fecl_3·6H_2O)as flocculant. The factors affecting the separating efficiency such as the concentration of copper ion in bulk solution, the concentrations of surfactant and flocculant, and the gas flow velocity, were investigated. Thus the optimum condition of separation up to China's draining standard was determined. The concentration of copper ion in drained solution was measured with atomic adsorption spectrophotometer. |
