In this paper the optimum condition for Sb-I-S-Br-PADAP complex formation in the presence of iodide has been studied. The interference of other elements can be eliminated by extracted of complex with benzene from 0 .75N sulfuric acid. The detection limit is 0.02 ug/ml, and the color is stable for at least 10 hours.
