| Abstract: | A method was developed for the determination of monoethanolamine,diethanolamine and Diethanolmethylamine in the absorption liquid of CO2 by cation-exchange ion chromatography with charged aerosol detector（CAD）.Chromatographic separation was performed on a Dionex IonPac CS17（250×4 mm）,fomic acid and acetonitrile were used as eluent,respectively.The effects of the types of column,eluent,eluent concentration of organic alcohol amines were investigated.The linear ranges of the method for three alcohol amines were 1.0100 μg·mL-1,the correlation coefficients were 0.9996,0.9993 and 0.9992,and the detection limits（S/N=3） were 0.21,0.04,0.32 μg·mL-1 respectively.The method was successfully applied to determine organic alcohol amines in real sample.The recoveries of three organic alcohol amines after spiking were from 87% to 98%. |
