摘要
Abstract
Objective] To select the optimal digestion solution for determining Zn in soil by microwave digestion – FAAS.[Methods] micro-wave digestion –FAAS was applied.Hydrochloric acid +nitric acid +hydrofluoric acid and hydrochloric acid +nitric acid +hydrogen per-oxide solution were taken as digestion solution separately.And comparative analysis experiment was carried.[Results] In the process of determi-ning Zn in soil by microwave digestion – FAAS, the digestion was complete when using hydrochloric acid +nitric acid +hydrofluoric acid as digestion solution, but the absorbance was abnormal and irregularity was high, leading to failure of the experiment; hydrochloric acid +nitric acid +hydrogen peroxide solution as the digestion solution could dissolve most Zn element in soil and satisfy the analysis requirement .[ Conclu-sion] Taking hydrochloric acid +nitric acid +hydrogen peroxide solution as the digestion solution meets requirement of analysis precision in determining the soil Zn content.关键词
