摘要
用国标法与高温热解法同时测定土壤样品中的总汞,基于测定原理及测定结果进行对比分析。试验结果表明,采用高温热解法测定土壤中总汞含量有良好的效果,可以替代国标法(GB/T 17136-1997前处理方法)。高温热解法快速、准确且无药品试剂影响,重现性优于采用国标方法测定的结果。
Total mercury in soil samples were determined by national standard method and high temperature pyrolysis method, and the results were compared and analyzed. The results showed that high temperature pyrolysis method could replace national standard method(17136-1997 GB/T). High temperature pyrolysis method was fast and accurate, and its reproducibility was better than that of national standard method.
