Cover Story: Biopolymers (chitosan and alginate) can incorporate metal-ion species to yield ternary metal composites (TMCs) with enhanced adsorption properties. TMCs were prepared and characterized that contain Al3+, Cu2+, and Fe3+, respectively. The monolayer adsorption capacity (Qm) of the composites was evaluated with the anionic dye methyl orange (MO) and a cationic dye (methylene blue; MB). The Qm (MO) was 422 mg/g for the Al- and 467 mg/g for the Cu-TMC, compared with 42 mg/g for Fe-TMC. MB afforded insight into the role of the metal center and surface charge, where only the Fe-TMC shows appreciable MB uptake due to the prevalent (hydroxy) Fe species. This study provided novel insights into the coordination chemistry of the metal species and their role on the TMC adsorption properties. View this paper
