【Abstract】 In this paper a new method of two-channel flow injection system utilizing 721 spectre-photometer for the determination of cadmium using wjtfso-tetrakis [C 4- ( trimethylammonium ) phenyl ] -porphine has been established. The optimal experimental conditions have been investigated in detail.The method is provided with rapid, sensitive and selective characteristics. The relative error of the determination of cadmium ia synthetic samples is<3%更多还原
