摘　　要：本文报导了用电解酸化法制备二种不同系列的锰钒杂多化合物。(NH_4)_(4、5)H_(0.5)Mn~ⅣV_(11)O_(32)·12H_2O和(NH_4)_5HMn_3~ⅣV_(12)O_(39)·15H_2O。制备时不用外加酸和氧化剂,反应条件容易控制。文献未有给出上述第二个化合物的直接合成方法,是从重结晶第一个化合物的母液析出的晶体中机械分离得到,产率很低。本文给出了直接合成的方法。This paper gives a new method,electrolytic acidifiing method,by which 1:11 and 3 :12 systems heteropoly complexes of vanadium and manganese (IV) have been synthesized.In comparison with the way in literatures,this method does not need the additional acid and oxidizer and obtains respectively the two system salts by controning the electrolytic conditions.The other advantages of this method are:1.raising the productive rates;2.shortening the reaction time; 3.the products being easily purifide.
