土壤中重金属元素统一制备液测试方法的研究

摘要

针对目前不能同时检测土壤中总镉、总铬、总铅、总汞、总砷、总铜、总锌和总镍等现状,本试验通过对样品前处理、消解方法及消解条件的选择及优化,探索出一套可以同时消解和测定8种重金属元素检测方法,此方法具有操作简便、快速、准确、干扰少等优点,适用于大批土壤样品的测定,可提高土壤中重金属检测效率.%According to the status that the content of heavy metals in soil such as cadmium, chromium, lead, mercury, total arsenic, total copper, total zinc and total nickel, could not be determined simultaneously, we developed an accurate and efficient method for uniform detection of eight heavy metals in soil through optimizing the sample preparation, digestion methods and digestion conditions. This method could resolve uniform digestion and determination of eight heavy metal elements, and it was simple, rapid, accurate and less interference. The method was suitable for determination of a large number of soil samples, which could greatly improve the work efficiency.
