摘要
本文报导用硫磷混酸(1+1)在100℃水浴上加热能使Mn_2O_3和Mn_3O_4溶解,而MnO_2的溶解率却很小,据此建立了一个分别测定这些锰矿物的新方法。
The trivalent manganese ore is selectively dissolved in H2SO4-H3PO4 mixture (1+1) on boiling water bath and t-travalent manganese ore remains insoluble. A new procedure based on this fact for the determination of Mn2O3 Mn3O4 and MnO2 has been developed.
