“…Compared with other works, we used a new polymer to fabricate the porous membrane, and then the ability of porous membranes to remove lead ions under various conditions was studied experimentally. Moreover, the adsorption capacity for lead ions by porous membranes was higher than that of other literature [27,28,29,30,31,32,33].…”

“…However, the spontaneous precipitation of Pb(II) would come up and generate Pb(OH) 2 sediment when the pH value was 6 and higher. Therefore, after this experiment pH values were set as 5, which is also a familiar pH value in industrial wastewater [30]. Although the adsorption capacity would be reduced when the optimal pH value was not reached, the adsorption capacity was still considerable in general.…”

Porous materials with high specific surface area possess a broad application prospect in the treatment of wastewater. In this work, sulfonated poly(arylene ether nitrile) (SPEN) functionalized with a carboxylic acid group was successfully synthesized, which was subsequently transformed into SPEN porous membranes with cetyltrimethyl ammonium bromide (CTAB) as pore-forming agents to study the adsorption performance for lead ions in aqueous solution. Then, experiments were conducted to investigate the effect of pH, contact time and initial solution concentration on the adsorption performance of porous membranes, and the adsorption capacities of porous membranes with different content (0, 5 and 15 wt %) of CTAB were 183.60, 161.73 and 127.43 mg/g, respectively, which manifested that the adsorption capacity decreased with the increase of CTAB. The adsorption capacities of porous membranes increased with the increase of the initial concentration of lead ions, and the maximum reached was 246.96 mg/g. The simulation of adsorption kinetics revealed that the adsorption was accorded with the pseudo-second-order kinetic model and Langmuir equation, indicating that the adsorption process followed Langmuir monolayer adsorption. Thermogravimetric analysis demonstrated that the porous membranes had excellent thermodynamic properties both before and after adsorption. In addition, the change of adsorption peak in the Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR) spectrum indicated that the absorption performance of porous membranes for lead ions benefited from the chelation between lead ions and the carboxylic acid group on SPEN. Moreover, the porous membranes maintained excellent adsorption properties after circulating five times under the conditions of acidic or alkaline, and the cycle regeneration effect was outstanding.

“…2b ) shows two peaks at 184.8 and 182.4 eV, which are ascribed to Zr 3d 3/2 and Zr 3d 5/2 , respectively. 7 It can be also found that the Zr is uniformly distributed in PES matrix and quite matches with that of C and O in the EDS mapping of M2 ( Fig. 3 ), further verifying the successful loading of Zr-based nanoparticles within the membrane.…”

“… 1–3 Adsorptive MMMs containing various types of nanoparticle ( e.g. zinc oxide, 4 iron oxide, 5 titanium oxide, 6 Zr 7 and Ag 8 ) have been developed on the laboratory scale. These studies have proved that adsorptive MMMs can be used to remove contaminants from water, 9,10 but the development of adsorptive MMMs by traditional methods such as physical blending or dip-coating faces a number of challenges, including the agglomeration of nanoparticles within the MMM and the potential leakage of the nano-sorbent, 11,12 which could reduce the performance of the MMMs.…”

“…The maximum adsorption amounts of GO-PAA25 could reach as high as 329.37 mg g –1 , which was much higher than many other reported adsorbents. (e.g., Wei et al fabricated poly(ether sulfone) enwrapped hydrous zirconium oxide nanoparticles showing a maximum adsorbed amount of 119.2 mg g –1 ; Zhang et al prepared cellulose filament/poly(NIPAM- co -AAc) hybrids showing a maximum adsorption amount of 80.8 mg g –1 ) . Meanwhile, it was found that the adsorption amounts increased with the decrease of PAA content.…”

Recently, in order to increase and improve treatment efficacy of hemoperfusion, research and development of novel adsorbents have been paid much attention. Herein, threedimensional (3D) graphene oxide (GO) skeleton guided poly-(acrylic acid) (PAA) composite hydrogel particles (HPs) used for hemoperfusion were prepared by a core−shell template method. The 3D GO skeletons with millimeter-scale were first constructed with the assistance of templates, dissolvable poly(ether sulfone) hollow particles, which were prepared by a phase inversion technique; then, PAA hydrogels were formed and distributed on the surface of the 3D GO skeleton. The obtained HPs showed a special hierarchical pore microstructure, small size, and uniform spherical shape. Compared with pure PAA hydrogels, the swelling ratios of the HPs were significantly restricted, and the porosities were remarkably increased; the compressive stress and the elongation at break were improved at the same time. The hemocompatibility tests, including protein adsorption, hemolysis ratio, complement and contact activation, platelet adhesion, and clotting time, were carried out, and the results indicated that the HPs showed good hemocompatibility. The adsorption results indicated that the HPs exhibited good removal efficiency toward exogenous and endogenous toxins. In general, the suitable physical and mechanical properties and the excellent hemocompatibility and adsorption capacities made the composite hydrogel particle a promising candidate for novel hemoperfusion adsorbents.
