摘要
本文研究了用微波炉在自制聚四氟乙烯密闭容器内 ,用 NHO3- HF增压分解样品 ,既解决了样品分解的难题 ,又减少了污染。并于标准系列中外加基体元素消除了基本的干扰 ,以 FAAS测定 K2 O和 Na2
Heated in micro wave oven with a sealed container made of polytetrafuroethylene,the experimental sample was dissolved by using HNO 3 HF as pressurization.This method decreased the contamination and solved the difficult problem of sample dissolution.The addition of basic elements to the standard series eliminated the interference.In this way,the K 2O and Na 2O can be measured by means of FAAS.
