Open publisher page 0 citations

Abstract

The Hg content is determined usually with atomic absorption spectrom ter,Hg analyzer.In this paper,we have a discussion about the testing method of trace Hg in soil with AFS-230E atomic fluorescence spectrome ter,which is characterized by the simple,rapid operation,high sensitivity,little disturbance of matrix and stable analysis result,etc.The recovery of testing Hg 90%~105%,limit of detection 0.00005 mg/L,which can meet the requirement of trace Hg test of soil in planting field.
