海绵钛中氯的测定,日常分析多采用氯化银浊度法,方法快速,但操作条件严格,重现性较差。我们利用氯离子选择性电极进行了海绵钛中氯的测定。对电极的响应、动态平衡、选择性、pH范围等进行了试验研究。结果表明该法准确、简单快速。适用于海绵钛中含量0.01～0.x%的氯的测定。主要试剂及仪器氯标准溶液浓度为1M,其他浓度的标 Sponge titanium chloride determination, routine analysis of the use of silver chloride turbidity method, the method is fast, but the operating conditions are strict, poor reproducibility. We used chloride ion selective electrode for the determination of chlorine in sponge titanium. Electrode response, homeostasis, selectivity, pH range were studied. The results show that the method is accurate, simple and fast. For titanium sponge content of 0.01 ~ 0.x% of the determination of chlorine. The main reagents and equipment Chlorine standard solution concentration of 1M, the concentration of the standard
