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,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0.010～0.030mg/L。用所建方法对实际F-T合成水相产物中小分子有机酸分析的结果表明,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。
A method for organic acids determination of water phase in low temperature FischerTropsch（F-T）synthesis by ion ehromatography（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 mg/L. 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（Anderson-Schulz-Flory）product distributions of F-T synthesis.
