【摘要】 研究了用微波炉加热，过氧化钠-氢氧化钠熔融分解钨精矿的实验条件，利用分光光度法测定锰，并与酸溶法进行了对照。实验表明：采用微波加热，碱熔融分解钨精矿制备试液测定锰，结果可靠，可提高分析速度。更多还原

【Abstract】 The determination method of manganese in tungsten concentrate using alkaline fusion method heated by microwave oven was briefly described. The optimum quantity edded of mixed fluxing agent(Na2O2-NaOH) aam time heated of the sample were investigated. The determination result of Mn shows the method is as reliable as acid decomposition method.更多还原
