摘　　要：用环己烷、环己烯和苯分别配制3种类型的模拟水样,采用四氯化碳萃取红外分光光度法测定水中的油含量,研究了盐析效应对饱和烃、不饱和烃与芳香烃含量测定的影响。结果表明,盐析效应对饱和烃含量测定的影响非常小,而对不饱和烃与芳香烃含量测定的影响比较大。在此基础上研究了盐析效应对石化废水和油田废水中油含量测定的影响。Three types of simulated water samples have been prepared with cyclohexane,cyclohexene,and benzene. The oil content in water has been extracted with carbon tetrachloride and determined by infrared spectrophotometry. The influences of salting out effect on the content determination of saturated hydrocarbon ,unsaturated hydrocarbon and aromatic hydrocarbon are studied. The results show that the salting out effect has little influence on the content determination of saturated hydrocarbon,but has greater influence on the content determination of unsaturated hydro-carbon and aromatic hydrocarbon. Based on this,the influence of the salting out effect on the oil content determina-tion of wastewater from petrochemical plants and oilfields are studied.
