| Abstract: | In this paper,the method and the principle of making the metal-TPPS-sol-gel film has been studied.Cd2+,Zn2+,Hg2+ is measured by sol-gel film.The linear range is 10～500 μg/L,8～700 μg/L and 10～700μg/L.Minimum detection limit is 1.2 μg/L.The Cd2+concentration of the Nanhu water is 20 μg/L.Relativeaverage deviation is 14.9%. |
