Abstract
5-(p-Dimethylaminobenzylidene)-rhodanine is used to determine 0.5 to 6 p.p.m. of platinum colorimetrically, after reduction of platinum IV with ascorbic acid. Platinum can be determined in the presence of a 10-fold excess of palladium; low concentrations of the other platinum metals, except rhodium, do not seriously interfere.Keywords
