Extraction of Co(II) ions from aqueous solutions with thermally activated dolomite

It was found that thermal activation of dolomite at 700–900°C may increase the sorption capacity of the samples up to 520 mg g −1 . It was shown that the most effective sorbent for Co 2+ ions may be obtained by calcination of dolomite at 800°C, which allows under dynamic conditions (20 m h −1 ) puri...

Description
Summary:	It was found that thermal activation of dolomite at 700–900°C may increase the sorption capacity of the samples up to 520 mg g −1 . It was shown that the most effective sorbent for Co 2+ ions may be obtained by calcination of dolomite at 800°C, which allows under dynamic conditions (20 m h −1 ) purifi cation of 500 column volumes of an aqueous solution with a Co(II) concentration of 10 mg L −1 to the maximum allowable concentration.
