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.
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.
