摘要
本文研究了离子色谱法测定环境水样中阴离子时样品的一般处理方法。该方法以固体无水碳酸钠处理水样并以酚酞指示剂指示处理的终点，以邻苯二甲酸除去样品碱性干扰，以活性炭吸附水样中的有机物和酚酞指示剂。研究测试和监测实践的结果表明，该方法应用于环境监测简单可靠。
The paper detailed the general method of sample treatment for the determination of anions in environmental water samples with ion chromatography.The solid sodium carbonate(anhydrous)was used for the treatment of water samples with phenolphthalein as indicator to indicate the end point of the treatment.Phthalic acid was used to erase the basic interference from samples,and activated charcoal was used for the adsorption of organic substances and the indicator.Test results and monitoring practice show the method is practical and reliable.
