Green adsorbents for water remediation: Removal of Cr(vi) and Ni(ii) using Prosopis glandulosa sawdust and biochar

Green Processing and Synthesis, Год журнала: 2025, Номер 14(1)

Опубликована: Янв. 1, 2025

Abstract Potentially toxic elements like Cr +6 and Ni +2 cause severe health hazards. Therefore, the current work was aimed at cleaning water using Prosopis glandulosa raw sawdust (SD) its derived biochar (AC). Both adsorbents were characterized via SEM, FTIR spectroscopy, EDX, TGA applied for effective removal of Ni( ii ) Cr( vi optimum values experimental conditions, mechanism assessed adsorption isotherm kinetic models. The correlation coefficient R 2 confirmed pseudo-second-order kinetics preferred Freundlich model. Maximum iv obtained a pH 4.0, bio-sorbent concentration 0.8 g·L −1 , temperature 50°C 50 min with metal 110 ppm, while maximum contact time 70 130 ppm in above-mentioned conditions. results isotherms model revealed that processes involved multilayer formation on biosorbent’s heterogeneous surface. Also, their thermodynamic investigation showed process is spontaneous exothermic and, therefore, can be effectively utilized to remove from water.

Enhanced removal of Pb(II), Zn(II) and Cd(II) ions by insolubilized humic acid: Characterization and sorption behaviors

Desalination and Water Treatment, Год журнала: 2024, Номер 320, С. 100604 - 100604

Опубликована: Июль 14, 2024

Humic acid from Tafila soil in Jordan has been extracted and insolubilized to investigate the effectiveness for adsorption removal of heavy metal ions (Pb(II), Cd(II), Zn(II)) aqueous solutions. Fourier transform infrared spectroscopy, thermal gravimetric analysis, elemental X-ray diffraction, scanning electron microscopy, differential calorimetry were used characterize sodium form Insolubilized Acid (INaTAHA). Evaluating its capacity under various conditions (pH, temperature), Pb(II), Zn(II) by INaTAHA was investigated. It observed that a maximum uptake as follows: Pb(II) > Cd(II) ion increased with pH reaching peak at = 6. Kinetic studies results demonstrated level requires an equilibrium time 24 hr each fitting pseudo-second-order model. The activation parameters Ea, ΔG‡, ΔH‡, ΔS‡ also calculated. findings show physisorption is mode adsorption. Using column technique, percent Cd(II). 1.0 M HNO3 produced best recovery according desorption studies.
