To prevent indium hydrolysis and to ensure EDTAtitration in acidic condition, the effect of seignette salt dose on indium solution of ITO waste material is studied.
Testing the content of sulphate with EDTAtitration method can directly influence its precision because whether the capacity of barium mixed liquid of magnesium is added suitably.
用EDTA滴定法检测硫酸盐,钡镁混合液的加入量是否适当,直接影响到检测的精确度。
