微波加热技术在重量分析法中的应用
Application of Microwave Heating Technique in Gravimetry
【摘要】 本文报道了用微波加热技术代替传统灼烧方法进行重量分析的新方法。用于分析纯试剂Na2SO4和铜铅锌矿石中S的测定表明本方法不但可大大节省分析时间,而且具有很好的准确度和精密度。此外还进行了微波炉Na2O2—ZnO熔融分解矿样的研究。
【Abstract】 We report a novel application of microwave heating technique as an alternative to the conventional ignition method in gravimetry. The determination of element sulphur in A. R. grade Na2SO4 reagent and Cu-Pb-Zn ore indicates that the proposed method has the advantages of saving time as well as very good precision and accuracy.The Na2O2- ZnO fusion of sample using microwave oven was also studied.
