摘要
Microwave digestion method was used to decompose the soil samples and inductively coupled plasma-optical emission spectrometry (ICP-OES) and graphite furnace atomic absorption spectrophotometry (GFAAS) were used to determine nine elements of Cu, As, Pb, Zn, Co, Cr, Mn, Ni and V in sample solution. Sample digestion and instrument measurement conditions were optimized through the experiments. The detection limits of the method for the elements are from 0.16 μg/g to 2.52 μg/g. Recoveries for different elements are between 95.2% and 107% with precision of 2.03%~9.79% RSD (n=7). The method provides the advantages of lower detection limits, simple operation and high efficiency.
