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.
The color reaction of Pd (Ⅱ) with DBC-chlorophosphonazo was carried out in sulfuric acid medium by heating. The color reaction and flow injection analysis were combined to study the various factors affecting the flow injection color system. A flow injection analysis method for palladium was established, which allows the direct determination of palladium in secondary anode slime and chloride residue without isolation.
