纯金属钛和riCl_4中硫的测定方法报道不少,但灵敏度均较低,且操作冗长。本文在研究S~(2-)阴极溶出伏安法的基础上拟定了灵敏的测定方法。以磷酸-磷酸亚铴为钛溶剂兼作其中硫还原剂。钛及TiCl_4中硫的分析灵敏度分别为n×10~(-5)%和n×10~(-4)%,均较传统方法高百倍。仪器与试剂 1 H_2S蒸出器,其示意如图1 Determination of pure titanium and riCl_4 sulfur reported a lot, but the sensitivity is low, and the lengthy operation. In this paper, S ~ (2) cathodic stripping voltammetry on the basis of the development of a sensitive assay. Phosphoric acid - phosphoric acid 亚 titanium solvent as both sulfur reductant. The analytical sensitivity of sulfur and titanium in TiCl 4 is n × 10 -5% and n × 10 -4%, respectively, which are all higher than the traditional method.
