摘　　要：采用RA-915M汞分析仪测定土壤和沉积物中总汞,建立了一种快速直接的分析测定方法。该方法测定土壤和沉积物样品时不需要任何消解处理,操作简单,成本低,测量时间较短。通过对标准样品和实际样品进行测定,结果显示该方法有较低的检出限(0.0024mg/kg)和较高的精密度(RSD≤10.5%),而且数据结果准确、可靠。A rapid and direct method was established to determine total mercury in soil and sediment by RA -915M mercury analyzer. This method did not need any digestion pretreatment. It is simple, low cost, and quick.The method was adopted to test standard and practical samples. The results displayed that the data were accurate and reliable with low detection limit (0. 0024mg/kg) and high precision ( R S D ^ 1 0 . 5 % ) .
