摘要
用电位滴定法对2,6-双(苦氨基)-3,5-二硝基吡啶(PYX)标准物质的纯度进行测定。PYX用二甲基甲酰胺溶解,以四甲基氢氧化铵的二甲基酰胺溶液为滴定剂。该方法的回收率和变异系数分别为100.0%和0.13%。
The 2,6 dipicrylamino 3,5 dinitro pyridine(PYX)pureness reference material had been certificated by potentiometric method.In the method PYX is dissolved with dimethyformamide(DMF),tetramethylaminonium hydroxide of DMF is used as standard titrimetric solution.The recovery and variation coefficient were 100.0% and 0.13% respectively.
