摘　　要：研究了制备金属-卟啉凝胶膜的方法、原理及制备solgel膜的最佳条件.用该法测定Cd^2＋,Zn^2＋,Hg^2＋的线性范围分别为：10-500μg/L,8-700μg/L和10-700μg/L.最小检出限为1.2μg/L,测得长春南湖水中Cd2＋的浓度为20μg/L,相对平均偏差为14.9%.In this paper, the method and the principle of making the metal-TPPS-sol-gel film has been studied. Cd^2＋ , Zn^2＋ , Hg^2＋ is measured by sol-gel film. The linear range is 10 - 500 μg/L, 8 - 700μg/L and 10- 700μg/L. Minimum detection limit is 1.2 μg/L. The Cd^2＋ concentration of the Nanhu water is 20μg/L. Relativeaverage deviation is 14.9%.
