Abstract

Mesoporous magnetic ion exchange resin (m-MIER) was synthesized using methyl acrylic glycidyl ester as monomer with the method of monomer polymerization. Its removal performance on the typical dissolved algal organic nitrogen was studied subsequent to some preliminary characterization. Magnetic ion exchange resin (MIEX^®) was studied as a comparison simultaneously. The results showed that the lab synthetic m-MIER was mesoporous with the main pore diameter was from 2nm to 60nm, chloride was identified as the exchange group. Compared with MIEX^®, m-MIER owned similar wet density, particle size, more abundant pore structure and greater exchange capacity (1.15g/cm³, 150~200μm, 0.1852cm³/g, 3.16mmol/g vs, 1.20g/cm³, 150~180μm, 0.0184cm³/g, 2.23mmol/g). The results of XPS indicated that the major component of the core was Fe₃O₄, and the m-MIER was quaternary ammonium anion exchange resin. The m-MIER exhibited better removal effects on the typical dissolved nitrogen derived algae cells compared with MIEX^®and the removal rate was highly relevant with the categories of the dissolved organic nitrogen.
