摘要：
Isonitroso-4-methyl-2-pentanone (HIMP) is proposed as a new reagent for extraction and photometric determination of Pd(II). The reagent forms a yellow complex with palladium in the pH range 4.0-5.0. The complex extracted into chloroform was measured at 330 nm. The molar absorptivity was found to be 5.37 x 10(3) 1 mol(-1) cm(-1) and Sandell's sensitivity 20 ng cm(-2). Beer's law was obeyed over the concentration range 0.1-10.0 mu g/ml of palladium. The method is applicable for palladium estimation in Ores and catalysts.
