连续流动分析仪测定水中阴离子洗涤剂的方法

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0～2.000 mg/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0.010 mg/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.%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.
