提出离子色谱法测定剑麻叶中氯离子的方法：剑麻叶样品在超声波振荡条件下用水进行浸提，经炭黑小柱对提取的水溶液进行净化之后，采用离子色谱测定。经大批样品的实验测定结果证明，本方法平均回收率在95％～106％，RSD小于0．45％。该方法具有简单、重复性好、灵敏度高、准确性好等较多优点，适用于剑麻样品分析。

A method for the determination of chlorine (C1-) in sisal leaves was established with ion chromatography. The sample was extracted with water by ultrasonic method, and purified by SPE on carbon black micro-column, then determined with ion chromatography. Tests for recovery and precision were made, giving values of recovery ranged from 95%-106%, RSD was less than 0.45%. The method is simple, accurate, stable and precise. It can be easily and conveniently adopted for the routine quality control analysis.
