摘要：

研究了连续流动分析仪测定水中阴离子洗涤剂的方法.实验结果表明,在0～2.000mg/L线性区内该方法具有较高的精密度和准确度,其最低检出限为0.010mg/L.与手工亚甲基蓝分光光度法相比,该方法具有自动进样、分析速率快、试剂耗量低等优点,可应用于大批量常规地表水样的分析.

Abstract:

The determination of anionic detergent in water with continuous flowing analyzer has been studied.The experimental results show that the method has higher precision and accuracy within 0-2.000 mg/L anionic detergent in linear area，and the lowest detection limit is 0.010 mg/L.Compared with the manual methylene blue spectrometric method，the advantages of it are auto-sampling，rapid analysis speed and lower reagent consumption，etc.It can be applied to the analysis of large batches of surface water samples.

Key words: continuous flowing analyzer, anionic detergent, spectrometric method
