GB/T6682分析实验室用水规格和试验方法

3术语和定义

本文件没有需要界定的术语和定义。

4原理

人造革合成革中偶氮二甲酰胺经二甲基亚砜、丙酮、二氯乙烷水浴搅拌萃取浓缩，用高效液相色谱

分析，以偶氮二甲酰胺标准品保留时间定性，外标法定量。

5试剂和材料

5.1偶氮二甲酰胺标准品（C2H4N4O2，CAS号：123﹘77﹘3）：纯度大于99.0%（质量分数）。

5.2二甲基亚砜：分析纯。

5.3丙酮：色谱纯。

5.4二氯乙烷：色谱纯。

5.5乙腈：分析纯。

5.6混合溶剂：量取30mL二甲基亚砜、770mL丙酮、200mL二氯乙烷配制成混合溶剂。混合溶剂

应室温保存，有效期一个月。

5.7氮气：≥99.99%。

5.8水：应符合GB/T6682中二级水的规定。

5.9偶氮二甲酰胺标准储备液（1.0mg/mL）：准确称取适量的偶氮二甲酰胺标准品，用二甲基亚砜配

制成含量为1.0mg/mL的标准储备溶液。室温保存，有效期一个月。

5.10偶氮二甲酰胺标准溶液：移取适量体积的偶氮二甲酰胺标准储备液，用乙腈稀释，配制成所需含

量的系列标准溶液，现用现配。

5.11微孔滤膜：0.45μm。
