摘要
本文提出用离子色谱法测定水果及其树叶中氯含量的方法,在IC-PAK阴离子柱上,用4 mmol/L邻苯二甲酸(pH4.5)作流动相进行洗脱,电导检测器检测。方法简便、快速,灵敏、准确。氯的最小检出量为0.14μg,相对标准偏差为2.4%,回收率为99.4%。
A simple, rapid, sensitive and accurate method by the using ion chromatography for analy-sis of chlorine in fruits and Leaves was developed The detection limit, the relative standard de-viation and the recovery of this method were 0.14μg, 2.4% and 99.4% respectively.
