“…From Table 2, the order of lg K is Cr 3+ (6.897) > Cu 2+ (3.60) > Ni 2+ (3.49) > Zn 2+ (3.20) >> Na + (0.99), which is consistent with the above phenomena for the bivalent ion adsorption (Lawson et al 1984). And compared with other bivalent ions, the incon-3+ cluding -CONH2 and -OH, which has been confirmed from gruity in the lowest adsorption capacity for Cr is by virtue our previous study listed in literature (Zhang et al 2019).of the difference of the valence and the spatial combination…”

A lower expansive heavy metal adsorbent, high crosslinked sodium carboxyl methylstarch-g-poly (acrylic acid-co-acrylamide) resin (HCAA), has been prepared by enhancing the crosslinking degree of the traditional water-absorbing polymer under the graft copolymerization reaction. Further heavy metal adsorption experiments, morphology analysis, and structure characteristic observations indicate that HCAA resin has an excellent heavy metal adsorption properties for Cr 3+ , Cu 2+ , Ni 2+ , and Zn 2+ of 80.08, 158.07, 155.71, and 137.15 mg/g, respectively. The nanoholes in network structures of HCAA resin expanding in solution provide an effective diffusion and exchange channels for heavy metal ions and Na + . The adsorption process of HCAA containing -COONa is attributed to ion exchange process, and its essence is to form the coordination bond with heavy metals. The adsorption capacity differences of -COO − have been explained by using the coordination chemistry theory. In addition, the adsorption selectivity of an expansive adsorbent containing -COONa are heavy metals > H2O >> Na + . Our research puts forward an insight that increasing the crosslinker content on the basis of the traditional super absorbent resin can obtain a lower expansive adsorbent to heavy metal pollutants.

“…By modifying the proportion of interlinking, the pore size of the resin can be regulated, and the resin Adsorption mechanism of TACA resin Hydroxyl, carboxyl, and amino functional groups are present in the resin. Whose positions are important in forming complexes with transition metal ions, firstly chelation was done by using -NH 2 and -OH group via ionic and ion-dipole interactions 11,12,13,14 . The ability of resin to adsorb metal ions may therefore be very high, and it may be deduced that complexation with resin takes place by metal ions adsorption.…”

The natural polysaccharide-based resin of tamarind using functional group as 6-amino caproic acid has been synthesized by porath’s method. Their adsorption behavior also evaluated by determination of % adsorption of toxic metal ions from stock solution as well as industrial effluents by batch method and column separation experiment. Their physiochemical properties as bulk density, ion exchange capacity, and FTIR, were investigated. Using the batch equilibrium approach, Kd of five metal ions at various pH levels was investigated. The maximum removal % of metal ions of Cu+2, Fe+2, Zn+2, Cd+2, and Pb+2 at TACA resin were found at 97.97%,97.80%, 96.39%, 94.94%, and 91.90% respectively. Distribution ratio of these ions observed from pH 2 to 8 was Cu+2 > Fe+2> Zn+2> Cd+2 > Pb+2. The toxic metal ions from discharge samples of the metallurgical and mineral industries have been removed using ion exchange resins. Recovery of Zn (Ⅱ), Pb (Ⅱ), Cd (Ⅱ), Cu (Ⅱ), and Fe (Ⅱ) were obtained at 95.44, 96.27, 96.41, 98.82, and 100% respectively. The ion exchange capacity of TACA resin was found 2.24mmol/g

“…Subsequently (k4 = 2.92), Pb 2+ on the surface diffused into the interior of the MPMS through the macropores and mesopores. Finally (k5 = 0.07), Pb 2+ was adsorbed to the MPMS through the micropores, and as the adsorption proceeded, the slopes in Figure S2c decreased gradually as the intercepts increased, indicating that as the adsorption proceeded, the resistance of the MPMS to Pb 2+ adsorption increased [26]. Moreover, the fitting line in Figure S2c did not pass through the coordinate origin, indicating that diffusion was not the only limiting factor for the adsorption of Pb 2+ by MPMS [27].…”
