| 摘 要： | 对亚硝酸盐氮测定的清洁水样及1．00mg／L亚硝酸盐氮标准使用溶液分别进行了稳定性试验，试验表明，清洁水样置冰箱内至少可保存30d；1．00mg／L亚硝酸盐氮标准溶液可保存180d，大大延长了国标方法中规定的24h的保存期，既提高了工作效率，又节约了试剂，在实际工作中具有一定的可行性及推广性。

| Abstract: | The tests for the stability of nitrite nitrogen analysis of water sample and 1.00 mg/L standard solution of nitrite nitrogen are made.The results shaw that water sample can be stored in the refrigerator for at least 30 days while 1.00 mg/L standard solution of nitrite nitrogen for 180 days.It dramatically lengthens the storage time limit of 24 hours regulated by the national standard and helps to improve working efficiency and reduce solution consumption.It proves possible to be put into practical work and ... |
