Separation of Fe(II) from Co(II), Ni(II), Pb(II) Using Ameberlite IRA 400 Loaded with Alizarin Red S

뱃치법을 이용하여 음이온 교환수지(Amberlite IRA 400, Cl-형)에 Alizadin Red S(ARS)를 결합시킨 수지를 얻었다. 이 수지는 0.5M 이하의 무기산에서 안정하였으며 Fe(Ⅱ)이온의 흡착력이 다른 이온에 비해 컸다. Fe(Ⅱ)이온을 예비 농축할 수 있었으며 다른 이온으로부터 분리하는데는 용리액으로 pH4.5의 완충용액과 0.1M HNO3용액이 사용되었다.

An anion exchange resin which has Alizarin Red S (ARS) as functional group was prepared by batch method. The resin is stable in acidic solutions below 0.5 M hydrochloric acid, nitric acid and sulfuric acid and adsorption capacity of Fe(Ⅱ) ion on the resin was larger than other metal ions. The preconcentration and the separation of Fe(Ⅱ) ion from the mixture solution were carried out with the pH 4.5 buffer solution and 0.1 M HNO3 as eluents.
