【摘要】 羟基乙腈含量检测一般为紫脲酸铵容量滴定法,本文在此基础上,建立了电位滴定法。电位滴定法测定羟基乙腈含量不仅避免了紫脲酸铵滴定法中肉眼观察指示剂变色带来的误差,而且操作方法,精确度高。更多还原

【Abstract】 Potentiometric titration for the determination of hydroxyacetonitrile not only avoids the error caused by the discoloration of the indicator in murexide titration,but also has high accuracy in operation.The generally determination of glycolonitrile is capacity titration of murexide,on this basis,apotentiometric titration of glycollonitrile was developed.更多还原
