便携式X荧光分析仪快速测定土壤中Cd· Hg· As· Pb· Cr含量
Rapid Determination of Cd, Hg, As, Pb, Cr Content in Soil by Portable X-ray Fluorescence Analyzer
摘要
Abstract
Objective] The aim was to explore feasibility of portable X-ray fluorescenceanalyzer in environmental emergency monitoring.[Meth-od] The method of X-ray fluorescence analysis was used in the determination of standard samples , according to the key heavy metal elements of Environmental Quality Standard for Soil(GB15618-1995),including Cd, Hg, As, Pb, Cr, field measurement and laboratory sample analysis were conducted.The accuracy and precision of determining 5 kinds of heavy metals by the method were studied.[Result] The precision(RSD) of soil reference material determined by X-ray fluorescence method was 1.77% -22.90%.The relative deviation(RD) of the field samples was-42.0%-18.1%, RD of Cr was relatively small (from -21.2% to 10.5%); RD of As was larger (from -42.0% to 18.1%).[Conclu-sion] The portable X-ray fluorescenceanalyzer can play a guiding role in environmental emergency monitoring of soil heavy metals .关键词
