| 摘 要： | The novel chelating sponge modifed with hydroxamic acid groups was prepared by a grafting polymerization followed by a nucleophilic substitution reaction.Elementary analysis,SEM,FT-IR spectroscopy and XPS were used to characterize the spongy adsorbent（PVA-MA-HH）.Adsorption isotherm study indicated that PVA-MA-HH had high equilibrium adsorption capacity for Cu2＋.
