摘要
研究了采用配位滴定法检测菲汀质量的方法 ,并将用Th(NO3) 4 作标准溶液与用NH4Fe(SO4) 2 作标准溶液作了比较 实验证明 ,钍盐法明显具有操作简便 ,终点敏锐等特点 ,有很好的应用价值 .
The way of detecting the quality of phitin by complex titration is researched.In the research,the two different standard solutions -Th(NO 3) 4 and NH 4Fe(SO 4) 2- are compared.The experiment shows:Th(NO 3) 4 has such better characters as operating simply,and end point sensible,which have high application worth.
