Determination of monoethanolamine, diethanolamine and diethanolmethylamine in the absorption liquid of CO2 by ion chromatography with charged aerosol detector(离子交换电雾检测测定CO2吸收液中一乙醇胺、二乙醇胺、N-甲基二乙醇胺)
建立了阳离子交换-电雾检测器测定CO2吸收液中一乙醇胺、二乙醇胺、N-甲基二乙醇胺的分析方法.实验采用IonPac CS17阳离子交换柱，选用甲酸与乙腈溶液为淋洗液，并考察了色谱柱种类、淋洗液种类与浓度对分离测定有机醇胺的影响.所测3种有机醇胺的检出限分别为0.21、0.04、0.32 µg • mL-1，线性范围在1.0~100 µg • mL-1，相关系数分别为0.999 6、0.999 3和0.999 2，加标回收率为87%~98%.用所建立的方法测定了CO2吸收液中有机胺质量浓度，结果令人满意....
