【摘要】 本文采用过氧化氢和硝酸溶液，沸水浴法，消化置于比色管中的土壤样品，该方法与常规处理方法相比，具有消化速度快，重现性好，溶出率高等特点．处理一批样品仅用２小时，样品回收率９４％以上，溶样的重现精度和再现精度均小于５．０％，样品溶出量与强酸消化法无显著性差异．更多还原

【Abstract】 This paper presents a method of digesting sample of soil by hydrogenperoxide and nitril acid in a water bath.This method has its advantages as quilklydigesting speed,fine repeatability, high stripping rate and is superior to conventionalones.It only takes 2 hours to treat a group of samples.Sample recovery exceeds 94%.The precisions of both repeatability and rerroducibility are less than 5.0%.There isno distinguishable difference in amount of stripping from strong acid digestion.更多还原
