本文报告了4-[(5-氯-2吡啶)偶氮]-1.3二氨基苯(简称5-Cl-PADAB)与铂(Ⅳ)显色反应的条件和该试剂作分光光度法测定铂的可能性。经实验,溶液酸度为pH2.8~3.6时,5-Cl-PAPAB与铂(Ⅳ)形成水溶性紫
This article reports the conditions for the color reaction of 4 - [(5-chloro-2pyridine) azo] -1.3 diaminobenzene (abbreviated as 5-Cl-PADAB) with platinum (Ⅳ) and the reagent for the spectrophotometric determination of platinum possibility. The experiment, the solution acidity of pH2.8 ~ 3.6, 5-Cl-PAPAB and platinum (Ⅳ) form a water-soluble purple
