三氯偶氮胂的提纯、鉴定及其在水溶液中的离解作用研究

Study of purification and distinguish of TC-arsenazo and its dissociation function in water

建立了三氯偶氮胂的萃取提纯方法,纯品经色层分析、红外光谱分析、元素分析以及有效成分测定,均表明有效成分达95%以上.用分光光度法测定了三氯偶氮胂的六级离解常数,而且探讨了该试剂在高酸度下与金属离子显色反应的反应机理.

A new method of purifying TCarsenazo is established.The analysis of chromatography,infrared spectroscopy,elements and effective ingredients indicates that its effective ingredients add to 95% or more .Its six dissociation constants have been determined,and its color reaction mechanism with metal ions has been discussed.
