浮选分离法具有富集倍数高、方法简便等优点,是一种值得推广的有效富集分离手段。我们采用组合式浮选器,以铜试剂-十二烷基苯磺酸钠浮选分离法富集分离了排污水中的重金属离子。实验部分 1.浮选器:组合式浮选器(图1)的鼓泡与抽滤分别通过不同筛片完成,沉淀不直接 Flotation separation method has the advantages of high enrichment multiple, simple method and the like, and is an effective enrichment and separation method worthy of promotion. We use a modular flotation device, with copper reagent - sodium dodecyl benzene sulfonate flotation separation of heavy metals in wastewater effluent separation and separation. Experimental part 1. Flotation: The flotation and suction filtration of the combined flotation device (Figure 1) were completed by different sieves, respectively, and the precipitation was not direct
