【摘要】 采用微波辅助消解土壤,消解用酸的比例（体积比）为HNO₃:HF:HClO₄=5:4:0.5。采用HClO₄取得了很好的消解效果。消解液可以用于测定Cu、Zn、Ni、Pb、Cd、Cr、Hg、As 8种重金属。将3种标准方法三法合一,极显著提高了工作效率。更多还原

【Abstract】 Microwave was applicated for heavy metal digestion of soil.The proportion of acids is HNO₃:HF:HClO₄ =5:4:0.5（by volume）.Although HClO₄ is generally considered as inappropriate acid for microwave digestion,it was proved to be efficient for the digestion of soil.The liquor can be used to detect eight heavy metals,including copper,zinc,nickel,chromium,lead, cadmium,mercury and arsenic.Three standard methods were combined,and the work efficiency was dramatically improved.更多还原
