泡沫浮选用于分离混合物以及为了资源再利用而回收和分离溶液中某些微量组分。作为泡沫浮选的实际应用,对废水中存在的铜、镍与捕收剂的络合物用扩展的休克尔方法对其电子合成键状态进行了计算。当络合物形成时,不仅象二硫代氨基甲酸盐、二硫代碳酸盐、二硫代磷酸盐那样捕收剂的硫原子的电子转移给金属原子,而且捕收剂给出电子的能力也由于烷基的取代而增加。氨基二硫代甲酸镍以共振形式对于其稳定性的影响取决于各个共振形式的总能量。镍和铜对捕收剂中硫的亲和力比氧强,所以捕收剂对这些金属的捕收能力有下列顺序:二硫代捕收剂>一硫代捕收剂>羧酸盐捕收剂。
Froth flotation is used to separate the mixture and to recover and separate some of the solution’s minute constituents for reuse. As a practical application of froth flotation, the complex state of copper, nickel and collector existing in waste water was calculated by the extended Huckle method. When the complex is formed, not only the electrons of the sulfur atom of the collector such as dithiocarbamate, dithiocarbonate and dithiophosphate are transferred to the metal atom, and the collector gives electrons Also increases due to the substitution of alkyl groups. The effect of nickel dithiocarbamate on its stability as a resonance depends on the total energy of each resonance form. Nickel and copper have a stronger affinity for sulfur than the oxygen in the collector, so the collector’s ability to collect these metals is as follows: dithio-collector> monothio-collector> carboxylate collector .
