摘要

[目的]探究垃圾渗滤液中氟离子和氯离子的含量.[方法]用离子色谱法测定氟离子和氯离子标准物质(GSB07-3184-2014,204721)和8个垃圾渗滤液(样品1~8)的氟离子和氯离子含量.[结果]由测试结果可得,仪器的检出限、精密度、准确度和样品的回收率均能满足检测要求.[结论]氟离子和氯离子标准物质的测量结果表明离子色谱仪的精密度和准确度均符合要求,可以用来测定垃圾渗滤液中氟离子和氯离子.8个样品的测量结果表明,在垃圾渗滤液中氟离子和氯离子的含量均超出排放标准,排入环境之前需进行必要的处理,避免对水体和土壤造成污染.%[Objective] The research aimed to investigate the content of fluoride and chloride in landfill leachate. [Method] The contents of fluoride and chloride in standard materials (GSB07-3184-2014, 204741) and eight landfill leachate (Samples one to eight) were determined by ion chromatography. [Result] From the test results, the detection limit, precision, accuracy and sample recovery of the instrument can meet the testing requirements. [Conclusion] The measurement results of fluoride ion and chloride ion reference material indicate that the precision and accuracy of ion chromatography meet the requirements and can be used to determine fluoride ion and chloride ion in landfill leachate. The measurements of eight samples showed that the content of fluoride and chloride in the landfill leachate exceeded the discharge standard, and the necessary treatment should be carried out before being discharged into the environment to avoid water and soil pollution.
