In this study, for magnesium hydroxide adsorbents, hydrothermal doping strategies were used to change their surface and structural properties to enhance adsorption. A novel adsorbent was prepared and used to remove low concentrations (<100 mg ⋅ L−1) of Pb2+ from water. The structure of the adsorbent was characterized a series of characterization methods with X‐ray diffraction, scanning electron microscopy, thermogravimetric analysis, fourier transform infrared spectroscopy, nitrogen adsorption‐desorption isotherms, and X‐ray photoelectron spectroscopy. The results showed that the adsorbent was a whisker composed of magnesium hydroxide, carbonized chitosan and basic magnesium carbonate (BMC@Mg(OH)2/CCS) with a specific surface area of 84.35 m2 ⋅ g−1, much higher than that of pure magnesium hydroxide whisker (37.84 m2/g). The adsorption isotherm, kinetic, and thermodynamic properties of the adsorbent for lead ions were studied in detail by batch adsorption. The Langmuir model fits the adsorption isotherm better, and the adsorption capacity is 416.67 mg ⋅ g−1. The adsorption mechanism, which mainly involves chemical precipitation and ligand chelation, is discussed.

“…Adsorption is one of HMs treatment are widely applied because its low cost, high efficiency and environmentally friendly [4][5][6][7]. The surface phenomenon that mainly includes chemical, physical, and ion exchange are mechanism of adsorption [8][9]. Adsorption isotherms and kinetic models are the most convenient and widely used due to its provide important information of the adsorption properties such as maximum adsorption capacity and adsorption rate coefficient which its corespond to the performance of the adsorbents [10][11][12].…”

The isotherms and kinetic adsorption models for lead (II) in the mining pit water at Bangka on Shrimp Shells Waste Chitosan (Sw-Chi) was studied. The Sw-Chi from the dried shrimp (generally Penaeus semisulcatus species) waste were extracted via deproteinization, demineralization, decolorization and deacetylation steps at previous work. The chitin deacetylation values of Sw-Chi was 88.98% determined through FTIR spectra using baseline method. The initial lead (Pb (II)) concentration in this study was 0.41 ppm from open-pit water in Sungailiat district, Bangka Island. The performance of Sw-Chi adsorption on lead in the pit water with the ratio of 1:500 (w/v) in variation contact time while stirring at room temperature. The adsorption isotherms and kinetic models for lead in the mining pit water at Bangka follows the pseudo-second-order (PSO) and the Freundlich isotherm (F-Isoth) model. The adsorption mechanism may be due to Van der Waals forces and formed lead multilayer onto Sw-Chi surfaces.

“…Bahadur et al (2022) assessed that impact of fuller earth, rock phosphate, and biochar on remediation of Cu, Zn, Fe, and Cd in heavy and less polluted soil and reduce their uptake by maize plant. Kandil et al (2023) studied the efficacy of hybrid composite of fuller's earth, aluminium silicate and chitosan on removal of Pb(II) and Cu(II) in aqueous solution. The main objective of the present study was to assess the efficacy of press mud compost and fuller earth alone and mixed at 0.5 and 1 % on the stabilization of Pb and Cd in Sharafi Goth and Malir polluted soils, and reduce the uptake of Pb and Cd in the root and shoot by sorghum plant.…”

The aim present work was to examined the alone and combined impact of press mud compost and fuller earth at 0.5 and 1 % dosage on immobilization of Pb and Cd in Sharafi Goth and Malir polluted soils and reduce their uptake by sorghum plant. The results revealed that sorghum dry biomass yield was observed by 41.47 and 58.8 % with press mud compost (PMC) 1 % + fuller earth (FE) 1 % in Sharafi Goth soil and in Malir polluted soils than control. The immobilization of Pb was observed by 88.0 and 93.52 % with PMC 1 % + FE 1 %, and Cd was immobilized by 90.36 with PMC 1 % + FE 1 % and 78.0 % with PMC 0.5 % + FE 0.5 % in Sharafi Goth and Malir polluted soils than control. The uptake of Pb and Cd in shoot and root by sorghum was reduced both soils with application additives. The studied amendments increased the soil chemical properties such as electrical conductivity (EC), pH, cation exchange capacity (CEC), organic matter (O.M) and CaCO3 than control soil. The results of redundancy analysis showed that soil O.M had positive correlation with plant dry biomass, whereas EC, pH, CEC, O.M and CaCO3 showed negative correlation with Pb and Cd in soil and Pb and Cd in plant soot and root biomass. The results of present study indicated that press mud compost alone and in combined form shown positive impact on plant growth, immobilize Pb and Cd in both soils and reduced their uptake by sorghum plant. Future long-term field experiments must be carried out in multi-metals polluted soils and cultivate different genotypes.
