PURPOSE:To treat ions effectively by putting a magnetic material carrier containing chelate functional group into solution containing metal ions, attracting and separating ions in the solution. CONSTITUTION:N,N'-methylene-bis-acrylamide and a crosslinker, hydroxymethyl methacrylate as monomer, is copolymerized with the suspension containing magnetite particles. By mixing adequate organic molecules in said copolymerization in a manner to form chelate functional group, a magnetic material carrier containing chelate functional group is formed. Said magnetic material carrier containing chelate functional group is put into the solution containing ion components such as heavy metal ions or the like and the ion components are attracted. Then, the carrier which attracted metal ions is separated from the solution. A collecting agent can be recovered by magnetic separation, and the collecting agent can be regenerated and reused. |
