摘 要: 研究了DBC-偶氮胂在H_2SO_4介质中与钯(Ⅱ)的显色反应,建立了钯的流动注射分析新方法,并用于直接测定二次阳极泥和氯化渣中的钯。 A flow injection analysis method has been developed with the spectrophotometric determination of palladium. The system involves the messurement of the absorbances of palladium-DBC-Arsenazo complex at 625 nm. The limit of detection for palladium is 0.15μg/ml. Sample solution could be analysed at the rate of 60 per hour. The method has been applied to determine palladium in anode mud and chlorination residue with satisfactory results.
