Abstract
An adsorbent and a method of preparing the adsorbent are described. The adsorbent includes a 2-anthracene ammonium magnetic ionic liquid (MIL), and a [FeCl]or a [CoCl]ion. The adsorbents, 2-anthracene ammonium tetrachloroferrate (III) ([2AA] FeCl) and 2-anthracene ammonium trichlorocobaltate (II) ([2AA] CoCl), are prepared by protonation of 2-aminoanthracene, followed by complexation with FeCl/CoCl. The adsorbent of the present disclosure is effective in removing contaminants such as heavy metal ions from an aqueous system in a cost-efficient and selective manner.
