摘要： 建立了低温F-T合成水相产物中小分子有机酸的离子色谱测定方法。方法包括样品前处理、定性定量参数的确定、检出限等。该方法具有良好的线性和精密度，加标回收率为99%~101%，最小检测限为0.010~0.030 mg/L。用所建方法对实际F-T合成水相产物中小分子有机酸进行分析，结果表明，低温F-T合成水相中小分子有机酸的分布符合F-T合成产物的ASF分布规律。

Abstract: A method for organic acids determination of water phase in low temperature Fischer-Tropsch (F-T) synthesis by ion chromatography (IC) was developed including sample pre-treatment, the qualitative and quantitative parameters and the detection limits. Said method possessed good linearity and precision, recovery rates of adding standard material were in the range of 99%~101%, the minimum detection limits of analytes were 0.010~0.030 mgL-1. This method was applied to determine the organic acids of water phase in low temperature F-T synthesis, and results showed that the organic acids distributions accorded with the ASF (An Derson-Schulz-Flory) product distributions of F-T synthesis.
Key words: organic acids, ion chromatography, determination, low temperature, Fischer-Tropsch synthesis
