An environmental-friendly magnetic bio-adsorbent for high-efficiency Pb(Ⅱ) removal: Preparation, characterization and its adsorption performance

Current Development of Sorbents Derived From Plant and Animal Waste as Green Solution for Treating Polluted Aqueous Media

“…However, each of those techniques has its own advantageous and disadvantageous features. When it comes to consider some aspects like lower energy consumption, simple operation, high efficiency, and environmentally friendly behavior, adsorption can still be regarded as one of the best methods [14,15].…”

An Amberlite IRA-400 Cl− ion-exchange resin modified with Prosopis juliflora seeds as an efficient Pb2+ adsorbent: adsorption, kinetics, thermodynamics, and computational modeling studies by density functional theory

“…11,12 Plant waste has been directly used as an adsorbent in adsorption studies, e.g., mustard husks, 6 papaya wood, 9 and saltbush leaves. 13 Ion-exchange resins have played an exceptional role in metal recovery and separation, and they are widely used for pre-concentrating and removing heavy metal ions from wastewater. [14][15][16] However, efficiency and selectivity are key issues in this research area.…”

Optimization of Pb (II) Ion Removal from Synthetic Wastewater Using Dead (Chlorophyta) Macroalgae: Prediction by RSM Method

“…4) show that after Pb (II) ions treatment, the peaks at 2352.3, 2305.91, and 2127.93 cm -1 indicated slight variations that emerged in triple bond areas. Yet some peaks in the fingerprint region (from 1417.86 to 1415.27 cm -1 region, 1018.94 to 1030.91 cm -1 , 872.57 to 884.91 cm -1 , and 604.69 to 601.54 cm -1 region) exhibited a noticeable shift, indicating that hydroxyl, amino, and carboxyl groups were involved in Pb (II) adsorption [27]. Another researcher, Elgarahy et al who used various types of algae as bio-sorbents for heavy metals removal, supports these findings [28].…”
