Two novel chelating resins are prepared by anchoring diethylenetriamine bis- and mono-furaldehyde Schiff bases onto the macroporous GMA-DVB copolymer beads and utilized for the adsorption towards Cu(II), Co(II), Ni(II), and Zn(II). FTIR spectra show that Schiff base groups have been successfully introduced into the polymer matrix and the chelating resins can form complexes with the metal ions. The chelating resins show a higher adsorption capacity toward Cu(II). The conductivity method can be used for determining the adsorption kinetics of the resins towards metal ions. The results show that the adsorption rates towards Cu(II) are much higher than those towards other ions and pseudo second-order and intraparticle diffusion models can be applied to treat the adsorption amount-time data.
