【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。更多还原

【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.更多还原
