摘要
本文根据高价锰与钒(Ⅵ)之间的氧化还原反应,研究了用BPHA-CHCl_3萃取光度法测定钒(Ⅴ),以间接计算锰矿石中微量有效氧(MnO_2)的分析方法.用于测定生产样品中含量≥0.01%MnO_2,效果较好.
An indirect determinatio'n of micro amount available oxygen in manganese ore by extraction photometric determination of V ( Ⅴ ) with BPHA-CHCl8 that is based on the redox reaction between Mn( Ⅳ )and V ( Ⅳ ) has been studied.The method is suitable for the deter mi nation>0.01% MnOt in manganese ore.
