“…Many adsorbents, such as mesoporous silica [10][11][12] , porous resin [13,14] and activated carbon [15,16] , have been developed for removing toxic metal ions from polluted wastewater. To facilitate the efficiency of removing toxic metal ions, functional groups, such as carboxyl [17,18] , amine [19] , amidoxime [20] and thiol [12] , have been incorporated into porous adsorbents. However, the necessity for a multi-step synthesis of these functionalized porous polymers may potentially limit their further applications.…”

“…Porous polyelectrolytes are effective for their removal because of the ion–polyelectrolyte interactions. Zhang and co‐workers grafted PAA chains onto a porous poly(glycidyl methacrylate) monolith, and the resulting system showed a Cu 2+ adsorption capacity as high as 35.30 mg g −1 as a result of favorable complexation with the numerous carboxylate groups in the monolith 72. Chen and co‐workers prepared negatively charged porous polyacrylonitrile polymers with improved adsorption capacities for Hg 2+ , Ag + , and Cu 2+ 73.…”

The past decade has witnessed rapid advances in porous polyelectrolytes and there is tremendous interest in their synthesis as well as their applications in environmental, energy, biomedicine, and catalysis technologies. Research on porous polyelectrolytes is motivated by the flexible choice of functional organic groups and processing technologies as well as the synergy of the charge and pores spanning length scales from individual polyelectrolyte backbones to their nano‐/micro‐superstructures. This Review surveys recent progress in porous polyelectrolytes including membranes, particles, scaffolds, and high surface area powders/resins as well as their derivatives. The focus is the interplay between surface chemistry, Columbic interaction, and pore confinement that defines new chemistry and physics in such materials for applications in energy conversion, molecular separation, water purification, sensing/actuation, catalysis, tissue engineering, and nanomedicine.

A novel porous membrane adsorbent was prepared by grafting of amino groups onto surface of eggshell membrane (Amino-ESM). Adsorption property of the Amino-ESM was investigated by removing Cu(II) ions from aqueous solution. Physicochemical properties of the pristine and the Cu(II)-loaded Amino-ESM were characterized by the FT-IR, SEM-energy dispersive X-ray, and contact angle goniometer methods. Meanwhile, effects of several important parameters, such as the amount of ammonia using for grafting, solution pH, temperature, contact time, and ionic strength, on adsorption behavior were studied by batch experiments. Adsorption capacity of the as-prepared Amino-ESM was about 2.5 times higher than that of the pristine ESM. The adsorption rate was rapid, and the equilibrium adsorption could be achieved within 60 min. Effect of ionic strength on the Amino-ESM adsorption was slight. Adsorption behavior was favorable and endothermic. Moreover, kinetics experiments indicated that the pseudo-first-order model displayed the best correlation with adsorption kinetics data. Besides, the intraparticle diffusion model and Crank model showed that the intraparticle solute diffusion is the rate-controlling step. Finally, adsorption experimental data could be better described by the Freundlich isotherm model. These results suggested that the prepared Amino-ESM could be an efficient adsorbent for removing Cu(II) ions from aqueous solution.
