“…In addition, the pore volume and the mean pore diameter of the GA were 0.0063 cm 3 g − 1 and 11.964 nm, respectively (Table 1). BET results implied that the GA can be mesoporous and this is in agreement with the reports [43,44]. Tis mesoporous and free form may lead to the adsorption of Au (III) ions (Figures 2(a)-2(c)).…”

A low-cost new green adsorbent (GA) was synthesized by tannin-rich pomegranate peel powder and formaldehyde for the fast and selective recovery of Au (III). It was characterized by Fourier transform infrared spectroscopy (FT-IR), Brunauer–Emmett–Teller (BET), elemental analysis (CHN), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS) (FE-SEM-EDS-mapping). The optimal values of influential factors were defined using a central composite design based on the response surface methodology (CCD-RSM). Adsorption properties were investigated by the kinetic, isotherm, thermodynamic, and interference of coexisting metal ions at optimum conditions. The experimental adsorption percentage with three repetitions under the optimized conditions such as pH = 2, adsorbent mass = 23 mg, Au (III) concentration = 32 m g L − 1 , and contact time = 30 min was 97% and the highest adsorption capacity of the GA was 315.450 m g g − 1 . The adsorption isotherm and kinetic were clarified by the Freundlich (R2 = 0.952) and pseudo-second-order (R2 = 0.998) models. The thermodynamic study (∆S° > 0, ∆H° > 0, and ∆G° < 0) revealed that Au (III) adsorption via GA was a facile, endothermic, and spontaneous process. The adsorption mechanism could be an electrostatic interaction and reductive adsorption. A small amount of GA (23 mg) adsorbed gold selectively and rapidly (30 min) from coexisting metals present in the waste printed circuit board (PCB) such as Ag, Al, Si, Zn, Pb, Ba, Ni, Ca, Mo, Co, Cr, Mn, Cu, Mg, Fe, and W. These results confirm the use of low-cost and high-efficiency GA to fast and selectively recover gold from waste PCBs.

The Removal of an anionic Reactive Blue 2 (RB2) dye in an aqueous solution was successfully achieved using a plasma-modified agricultural biomaterial waste. Sawdust from Moabi (Baillonellatoxisperma) and Sapelli (Entandrophragmacylindricum) was modified using non-thermal gliding arc plasma. The natural raw materials and plasma treated were characterized by Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), XRD, Chemical analysis by Fluorescence, Sorption Analyser, and Zetametry. Experimental parameters such as initial pH, contact time, adsorbent dose, initial RB2 concentration, and temperature were optimized. The results showed that the removal of Reactive Blue 2 dye was favorable at acidic pH conditions with the maximum capacity going from 172,85 to 200,91 mg.g-1 to 98,19 and 149,02 mg.g-1 respectively for raw and plasma-treated Sapeli and Moabi. The Avrami fractional-order kinetic provided the best fit to the experiments data and the thermodynamic adsorption data of untreated (SSB and SMB) and plasma-treated (SSM and SMM) sawdust followed an exothermic process. This work demonstrated that non-thermal plasma modified wood sawdust can be a good alternative absorbent for the removal of dye pollutants from an aqueous solution.

Purpose. To depollute water contaminated by phenol using the adsorption process in a batch reactor with valorization of olive pomace for the preparation of activated carbon to be used as an adsorbent. Methodology. In this present work, study on the influence of four principal parameters on the adsorption yield during the treatment of polluted water by the process of adsorption were studied, namely: the activated carbon mass, the contact time, the phenol initial concentration and the stirring speed. In addition, the process was optimized with full factorial designs using the response surface methodology by the MINITAB software. Findings. The phenol removal by adsorption on the activated carbon made from olive pomace makes it possible to achieve an adsorption efficiency of 91 % with the use of following optimal conditions: adsorbent mass of 0.48 g, a contact time of 110.80 min, a phenol concentration of 100.98 mg/L, and a stirring speed of 462.89 rpm. Contact time and adsorbent mass showed a positive effect on phenol removal efficiency. The principal effect results illustrate that all four examined factors significantly affected the phenol removal by olive pomace activated carbon with a confidence level of 95 %. Originality. The experimental data of the phenol adsorption on the olive pomace activated carbon were examined by adjustment of a second-degree polynomial model. This model is validated by a statistical method using an analysis of variance (ANOVA). Numerical optimization was performed by the desirability function to identify the optimal parameters for maximum phenol recovery. Practical value. In order to highlight a process for treating waters contaminated with phenol, we have chosen the processes that are considered to be best suited, which is adsorption with the recovery of a waste such as an adsorbent, which is prepared by physical and chemical activation of olive pomace. The full factorial design applied makes it possible to show the influence of each parameter independently and their dependencies, as well as to find the optimal experimental conditions quickly which lead to the realization of this process.
