摘　　要：本文报道了溶剂浮选法分离富集污水中痕量羧酸类有机污染物和胺类有机污染物的新方法。考察了溶液的pH值、通气速度、离子强度、浮选时间、相比以及不同溶剂对浮选效果的影响。在优化了浮选条件下溶剂浮选效率达到95%以上。采用本法对石化工业污水中的痕量羧酸类和胺类物质进行分离富集和鉴定,证明了该法的可行性。A novel method for separating and enriching trace acidic organic pollutants （carboxylic acids） and basic organic pollutants （amines） in waste water by solvent sublation has been proposed. The effects of pH of the solution, air flow rate, the ion strength of the solution, sublation time, the phase ratio and different solvents on the solvent sublation were investigated in details. In the optimal conditions selected,the solvent sublation efficiencies of the selected organic compounds are more than 95%. The experimental results show that this method is fast,simple, feasible,and applicable in the separation and concentration of carboxylic acids and amines in waste water.
