| 摘 要： | 采用0.45μm滤膜代替中速定性滤纸过滤地表水水样.在出现乳化时用干净带圈铜丝代替破乳剂异丙醇破乳,对阴离子型直链烷基苯磺酸钠(LAS)的国标检测方法进行了改进.结果表明:改进后的方法对样品的测定结果与国标方法无明显差异,方法的准确度、精密度均达到质量控制要求;分析步骤更简单,分析效率更高,更加适合测定地表水中的LAs...

| Abstract: | Water samples are filtered through 0.45 m microporous films first.It comprises extracting ion pair with CHCl3 twice,10 mL at a time.When emulsification occurs,It is an effective way to break of the emulsification layer by stirring with a clean copper wire.There is no significant differences between the result of samples determination by using the improved methods and the one by using international standard method.Both of the accuracy and precision of the method meet the quality control requirements,which is... |
