摘　　要：研究了阳离子表面活性剂及非离子表面活性剂对镉－５－Ｂｒ－ＤＭＰＡＰ的增溶作用．结果表明，阳离子表面活性剂对该体系增溶增敏作用显著，ε可达１．２１×１０５Ｌｍｏｌ－１ｃｍ－１．同时，利用Ｓ２－对该体系的褪色作用可间接测定Ｓ２－，建立的方法用于啤酒及工业污水中水溶性Ｓ２－的测定，结果令人满意．Solubilizations of cationic and nonionic surfactant on Cd(Ⅱ) 5 Br DMPAP complex were studied. Cationic surfactant is more appropriate. Trace amount of sulphide can be determined from its effect on the complex of Cd(Ⅱ) 5 Br DMPAP. Proposed method has been used to determine sulphide in beer and waste water. Results obtained are satisfactory.
