Using Cu(Ⅱ) as template and ethylene glycol bisglycidyl ether as crosslinking agent, a novel adsorption resin of chitosan condensed with salicylaldehyde has been synthesized. Its static adsorption capacity, kinetic and isothermal curves for Cu(Ⅱ) have been obtained. The adsorption capacity of the resin for Cu(Ⅱ) was 177.78 mg/g and selectivity coefficient K_{Cu(Ⅱ)/Fe(Ⅱ)} was 4.6, both much greater than that of resin without being treated by template. The resin cna be reused after simple regeneration.
