摘要
本文针对ICS-90离子色谱仪在水质监测不能一次进样测定阴离子,分析时间较长及淋洗液配比欠佳等问题;通过升级离子色谱仪原有的分析柱为新型复合柱,极大程度地改善了这些弊端;并经过多次实验获得,测定水中六项阴离子F^-,CL^-,NO_3^-,SO_4^(2-),CLO_2^-,CLO_3^-所应该采用的淋洗液配比Na_2CO_3比NaHCO_3为3.5:1时,实验效果为最佳,使离子色谱仪能更好地服务于水质检测工作。
In this paper, for the problems that the ICS-90 ion chromatograph can not detect the anion in the water injection, the analysis time is long and the eluent ratio is poor, by upgrading the original analytical column of the ion chro- matograph to a new composite column, these disadvantages have been greatly improved, and after several experiments, F- , CL-, NO_3 , SO_2-4 , CLO-2 ,CLO-3 in water should be used the eluent ratio of Na2C03 to 3.5：1 than NaHC03, and the ex- perimental effect is the best, so that the ion chromatograph can be better served the water quality testing work
