Determination of Mircro - Amout of Platinum in Catalyst by Catalyic Polarography

Chen Wen Xu Qiling Wang Zhenmeng Li Hongzhan Wu Xiaorong (Applied Chemistry Department of Chengdu Institute of Technology,Chengdu 610059)  
A method for the determination of platinum in a supporting solution of 0. 15mol/L diammonium diphosphate - 0. 5mol/L sulphuric acid - 0. 004mol/L hexamethylence by catalyic polarography has been established. The peak potential is - 1.02(uS. SCE). The peak height is linearly proportional to the concentration of platinum over the range of 1.0×10-5-8×10-3μg/ml. The detection limit is 5.0 × 10-6μg/ml. This method is simple, sensitive and good selectivity. The result is satisfactory when it is used to analyse catalyst and rocks.
