高分子量 Amine에 依한 鐵鑛石中 Titanium의 分離에 關한 硏究 = A Study on Seperation of Titanium with High Molecular Amine in the Iron Ore

다국어 초록 (Multilingual Abstract)

A liquid anion exchanger, Amberlite LA-1 diluted with xylene has been successfully used for the rapid separation of Ti(Ⅳ) from Fe(Ⅲ) in the Iron ore.
Since in 10N HCI the extractability of Amberlite LA-1-xylene solution for Ti(Ⅳ) is found to be nil, but that of Fe(Ⅲ) is very high, it is easy to separate the coexisting Ti(Ⅳ) by extraction from Fe(Ⅲ).
After extraction, the remaining Ti(Ⅳ) in the aqueous phase is determined colorimetrically using H₂O₂.
It has been found that the presence of such cations as Cr(Ⅵ), Ni(Ⅱ), Co(Ⅲ), Cu(Ⅱ), V(Ⅴ), Mo(Ⅵ), and Fe(Ⅲ) give no interference in the above procedure, and the same is true in the ease of such anions as nitrate, sulfate, phosate and perchlorate.
