研究了meso－四（对磺基苯）卟琳TPPS4与Ir4＋的荧光反应条件，建立了微量Ir的新方法。方法的检出限为20μg／L，测定范围为40～240μg／L。
The fluorescence reaction conditions of meso-tetrakis (p-sulfophenyl) porphyrin TPPS4 and Ir4 + were studied, and a new method of establishing trace amounts of Ir was developed. The detection limit of the method was 20μg / L and the determination range was 40 ~ 240μg / L.
