摘要
介绍了在硫磷混酸介质中,以硫脲为滴定剂,二苯胺磺酸钠为指示剂测定锰矿石、锰合金中锰元素的方法,用本法测得的结果与三价锰亚铁滴定法(硝酸铵、硫酸亚铁铵法)测得的结果基本一致。
The article introduces some ways,such as vulcanizing carbanmide by dripping to test the appointed Mn-ore and Mn in Mn ferro-alloy with binomial amine sulphur acid-sodium.We can get the same result as we did in triple ferrous-Mn by dripping(ammonium nitrate or ferrous-ammonium nitrate).
