1975年Koirtyofann将微波引入样品处理之中,但一直到1983年Matthes才提出用封闭容器微波消化样品,1986年Kingston和Jassie采用计算机系统对高温高压下封闭容器微波消化样品的一些基本参数进行了定量研究,确定了消解酸与微波能之间的基本关系,才使这一技术有了突破性的进展。目前,微波消化技术已广泛应用于地质、冶金、煤炭、石油、坏保等领域的分析工作中。本文针对生物样品的特点,改革了常用的微波消化方法,取得满意结果。材料与方法1．仪器设备MK-1型压力自控微波消化炉及高压密闭消化罐(上海新科微波技术应用研究所提供);聚四氟乙烯内胆系列(自制);马福炉;电热板;水浴锅;原子吸收分光光度计(AA-680型、日本岛津);Fe元素灯(日本岛津)。
In 1975, Koirtyofann introduced microwaves into the sample processing. However, until 1983, Matthes proposed microwave digestion of samples in sealed containers. In 1986, Kingston and Jassie used computer systems to quantify some of the basic parameters of microwave-digested samples of closed containers under high temperature and pressure Research, to determine the basic relationship between digestion acid and microwave energy, this technology has made a breakthrough. At present, microwave digestion technology has been widely used in the analysis of geology, metallurgy, coal, petroleum, bad security and other fields. In this paper, the characteristics of biological samples, the reform of the commonly used microwave digestion method, and achieved satisfactory results. Materials and methods 1. Equipment MK-1 pressure-controlled microwave digestion furnace and high-pressure airtight digestion tank (Shanghai Institute of Applied Microwave Technology); Teflon liner series (homemade); Mufu furnace; hot plate; water bath; atomic absorption spectrophotometry Meter (AA-680 type, Japan Shimadzu); Fe element lamp (Shimadzu).
