摘要：建立了用于分子筛废水中六亚甲基亚胺（Hexamethyleneimine HMI）含量检测的抑制电导离子色谱分析方法。样品经过滤稀释后直接进样，色谱条件：IonpacCS17（250mm×4mm）阳离子分析柱和IonpacCGl7（50mm×4mm）保护柱，流动相为10mmolfLH2SO。溶液，流速1．0mL／min，25斗L进样量，采用抑制电导检测器。HMI的线性范围是0．3～300mg／L，线性方程Y=0．083p＋0．033，线性相关系数为0．9999，相对标准偏差为0．22％，检出限（以信噪比s／N=3计）为0．003mg／L，加标回收率为96．6％～102．9％。
A method of ion chromatography （ IC ） was developed for the determination of HMI in the waste water produced by molecular sieve process. The waste water was diluted with deionized water and filtrated by a 0. 22 μm nylon filter membrane. The analytical column was a Dionex Ionpac CS17 （250 mmx4 mm）with a guard column Ionpac CG17（50 minx4 ram）. The eluent was 10 mmol/L H2SO4 with a flow rate of 1.0 mL/min. The detection was performed with a Dionex suppressed conductivity detector. The quantitative analysis was done with an external standard calibration curve. The linear range of HMI in the method was 0. 3 -300 mg/L （r2 = O. 9999）, the average recovery was 99. 4% with the relative standard deviation 0, 22%, and the detection limit （S/N = 3 ） was 0. 003 mg/L. The method has been applied to determination of contents of HMI in the waste water of molecular sieve process.
