【摘要】 本文通过大量试验对测定蔬菜中铅含量的三种前处理方法———HNO3-HClO4消化法、H2 SO4 H2 O2 消化法、微波干灰化HNO3 HClO4法进行比较研究 ,证明微波干灰化HNO3-HClO4法具有氧化完全 ,药品用量少 ,无污染等优点。
【Abstract】 There ways HNO 3 HClO 4 disappear and boil,H 2SO 4 H 2O 2 disappear and boil,microwave dustization HNO 3 HClO 4 disappear and boil were compared to study advantage of three mothods. It was proved that microwave dustization HNO 3 HClO 4 disappear and boil has many advantages in oxygenate fully ,few quantity of medicine use ,no contamination through many experient.
