金铂喷丝头中铂的测定

Determination of Platinum in Gold-Platinum Spinning Nozzle

采用氯化亚锡还原金、余量与铂络会形成稳定黄色络合物的比色方法分析金铂喷丝头中30％左右铂质量分数，结果准确、可靠．方法简便．

The colorimetric analysis system is emplonyed to anolysized, which the stannous chlonde is used to reduce the gold from the goldmlatinum spzining onzzle and the remnant of stannous chloride is combined with platinum to form the stable yellow complex compound. The method has the advantages of relable, accurant result and simple operation.
