摘要
通过全自动电位滴定法与佛尔哈德法对有机肥料样品中氯离子含量进行测定比较,结果显示,自动电位滴定法不受溶液颜色干扰,测定更为快速、准确,平均回收率为97.1%。此种方法缩短了前处理时间,使实验操作更为便捷。同时该法适用于植株中的氯离子含量的测定。
The chloride ion content in organic fertilizer samples were determined using both automatic potentiometric titration and Volhard method and they were compared in this study. The results showed that the automatic potentiometric titration was not influenced by solution color it was more rapidly and accurately than Volhard method,and the average recovery rate was 97. 1%. This method could shorten the pretreatment time,make the operation more convenient. By the way,this method could be suitable for the determination of chloride ion content in plants.
