土壤样品中总铬测定的微波消解方法研究

Research on Determining Total Chromium in Soil Sample with Microwave Digestion Method

本文主要研究了电热板/硫酸—硝酸—氢氟酸消解方法及密封式消解方法的特点.并把二者有机结合,从而形成一种用酸量少,环境污染少,准确度较高的消解方法。

We researched on characteristic of electric hot plate/sulfuric acid-nitric acid-hydrofluoric acid digestion method and sealed digestion method,and found out that combination of these two methods would make a new digestion method which using few acid,producing little pollution and being more accurate.
