摘要
采用定量的氯化钡与氢氧化钠一次性沉淀分离铝锰合金中的锰、铁等干扰元素 ,代替以往的先以六次甲基四胺分离锰 ,再以氢氧化钠分离铁的二次沉淀分离 。
The once precipitation separation of Mn and Fe, etc. in Al Mn alloy with BaCl 2 and NaOH was used for replacing the twice precipitation separation, in which at first Mn was separated by hexamethylenamine, then Fe by NaOH. Aluminium was determined by EDTA titrimetry.
