摘要
Pd(Ⅱ)与DBC-偶氮氯膦在硫酸介质中经加热发生络合显色反应,将此显色反应与流动注射分析技术结合,研究了影响该流动注射显色体系的各种因素,建立了钯的流动注射分析方法.用该方法可不经分离直接测定二次阳极泥和氯化渣中的钯.
A new flow injection analysis method was developed for the spectrophotometric determination of palladium. The system involved the measurement of the absorbances of palladium——(DBC-Chlorophosphonazo) complex at 620nm. The limit of detection for palladium is 0. 10μg/mL. Sample solution could be analysed at rates of 62 h-1. The method was applied to determine palladium in anode mud and chloride residue with satisfactory results.
