摘要
Abstract
In this paper, a method of direct determination of total mercury in soils was set up by use of RP91C-RA915M mercury analyzer. With regard to this method, solid sampling was directly conducted without fussy pre-treatment procedures of conventional methods such as acid digestion, acid driven, constant volume, etc.. Standard soil was used for drawing the working curves without the necessity of standard solution preparation by repeatable dilution of the standard stock solution. Moreover, detection limit, precision and accuracy of such method were determined. The result showed that with regard to this method, the detection limit was 0.25 g/kg; RSD was 1.98%~4.92%; determination of the standard samples was precise; and the standard recovery rate was 92.8%~106%.关键词
