现代的AAS、ICP-AES等分析仪器自动化程度高,测定速度快,有极好的灵敏度和测定精密度。为了充分发挥这些仪器的功能与优点,一般的常规试样分解和试液制备手段已难于满足要求。使用微波炉及密封聚四氟乙烯分解试样与常规试样分解方法比较,有显著地节省能源;极大地缩短溶样时间;增温增压,提高了酸分解试样的效率;减少所需试剂量,降低空白;具有最低的交叉污染及挥发损失;降低环境对试样的氧化作用,有利还原型物质(如亚铁)的分析测试等优点。1974年,将微波炉应用于实验室开始进行研究;1975年,Abu-Samra等人首次用微波炉对生物试样进行了湿法消化;1983年,出现了微波辐射酸溶地质样品的第一篇报道。大量研究表明,利用
Modern AAS, ICP-AES and other analytical instruments of a high degree of automation, determination of speed, excellent sensitivity and determination of precision. In order to give full play to the functions and advantages of these instruments, it is difficult to meet the requirements of conventional routine sample preparation and test solution preparation methods. Significant savings in energy use compared to conventional sample decomposition methods using microwave ovens and sealed teflon-decomposed samples; greatly reduced sample-dissolving time; increased warming and pressurization to increase the efficiency of acid-degraded samples; reduced need for reagents Reduce the amount of blank; with the lowest cross-contamination and loss of volatility; reduce the environment on the oxidation of the sample, the favorable reduction of substances (such as ferrous) analysis and testing advantages. In 1974, the microwave oven was applied to the laboratory to start the study; in 1975, Abu-Samra et al. First used microwave oven to digest the biological sample wetly. In 1983, the first report of microwave radiating acid-dissolved geological sample . Numerous studies show that utilization
