Selective adsorption and reusability behavior for Pb2+ and Cd2+ on chitosan/poly(ethylene glycol)/poly(acrylic acid) adsorbent prepared by glow-discharge electrolysis plasma

Synthesis of Mesoporous Calcium Silicate by Template Method and Its Adsorption Characteristic for Pb2+

“…As such, the Redlich-Peterson model was more suitable in describing the uneven surfaces of physical and chemical adsorption. Under the Langmuir adsorption model, the maximum adsorption capacity of MCS for Pb 2+ was 437.94 mg·g −1 at 293 K. This value was far higher than those of common adsorbents reported in literatures [17][18][19][20]. Given the intercept and slope of the fitted line in Figure 6, the adsorption thermodynamic parameters, such as ∆S, ∆H, and ∆G were calculated in accordance with Eqs.…”

Carbohydrate biopolymers, lignin based adsorbents for removal of heavy metals (Cd2+, Pb2+, Zn2+) from wastewater, regeneration and reuse for spent adsorbents including latent fingerprint detection: A review

“…This nanocomposite showed easy separation, better recovery and good purification for Pb 2+ ions in aqueous solution. Therefore, CS/PEG/PAA exhibited great regeneration ability and can be effectively applied in wastewater treatment [ 86 ].…”

Selective removal of lead ions from aqueous solutions using 1,8-dihydroxyanthraquinone (DHAQ) functionalized graphene oxide; isotherm, kinetic and thermodynamic studies

“…Consequently, the effects of coexistence ions are neglected, especially when the reusability of adsorbents having selectivity properties is considered. 77 Here, we put forward a facile approach to investigate the reusability of Fe 3 O 4 @DHAQ_GO in aqueous ion matrices containing different competitor divalent cations (Fig. 8)…”
