摘要
Abstract
Dithiocarbamate (DTCR) resin was synthesized using primary amine resin D309 in methanol-water solution way and characterized by FTIR and SEM .Adsorption mechanism and ion removal ability of DTCR were investigated by isothermal adsorption experiments and kinetics experiments . The results obtained from the equilibrium isotherms adsorption studies on three metal ions of Fe3+ ,M n2+ and Co2+ indicate that the adsorption conforms to the Langmuir isotherm equation .The maximal absorption capacity for Fe3+ ,M n2+ and Co2+ reaches up to 25.07 ,20.58 and 41.87 mg/g at 25 ℃ , respectively .The kinetics experiments show that DTCR has a high adsorption rate and the adsorption reaches equilibrium in 4 h .In the dual metal ions system ,the order of the adsorption selectivity for the three metal ions is M n2+ > Co2+ > Fe3+ . In the presence of Ca2+ and Mg2+ ,the removal rate of Co2+ stays at 97% ,and the removal rate of Fe3+ rises from 50% to 98% ,but the removal rate of M n2+ declines from 92% to 80% under competitive conditions .关键词
