“…Then, it would be very interesting to find out an application to reuse other precursors of AC production especially from agricultural wastes which are inexpensive, abundantly available and renewable materials [7]. From the literature, tobacco stems [8], rice husks [9], almond shells [10], citrus reticulate [11], corn cobs [12], coriolus versicolor [13], waste apricot [14], sawdust [15], date palm leaflets [16], rose waste [17], rosa gruss an teplitz [18], mentha arvensis [19], and cherry stones [20] were used to prepare ACs.…”

A B S T R A C TThe adsorption of a group of heavy metals namely, Zn 2+ , Ni 2+ , and Cd 2+ onto olive stones activated carbon (OSAC) was carried out in this work. The effects of different reaction parameters, such as the adsorbent dosage, contact time, shaking speed, and initial pH, on pollutant removal efficiency were investigated. Adsorption of Zn 2+ , Ni 2+ , and Cd 2+ was effectively explained by Langmuir and Freundlich isotherms. OSAC efficiently removed 99.03% Zn 2+ , 97.34% Ni 2+ , and 94.88% Cd 2+ at pH 5 and shaking speed 200 rpm. Surface characteristics of the prepared AC were examined by pore structure analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy. The Brunauer-EmmettTeller surface area, total pore volume and average pore diameter of the prepared AC were 886.72 m 2 /g, 0.507 cm/g, and 4.22 nm, respectively. The equilibrium data of the adsorption were fitted well to the Langmuir and the highest value of adsorption capacity (Q) on the OSAC was found for Zn 2+ 11.14 mg/g, followed by Ni 2+ 8.42 mg/g and Cd 2+ 7.80 mg/g. A pseudo-second-order model sufficiently described the adsorption kinetics, which indicated that the adsorption process was controlled by chemisorption. The results revealed that the OSAC has the potential to be used as a low-cost adsorbent for the treatment of wastewaters contaminated with heavy metals.

The study is aimed at assessing how the date palm wood fibers (DPWF) can be used for the removal of heavy metals from water. The study involved examination of the radical polymerization and graft polymerization parameters such as reaction period, reaction time, monomer volume, amount of the catalyst, and concentration of initiator to obtain the maximum yield of graft polymerization. Fiber and copolymer were characterized using SEM and FT-IR spectroscopy to ensure the completion of polymerization. Hydroxylamine hydrochloride was used for treating the grafted copolymers for the preparation of polyamidoxime chelating resin, which was then examined for removing the heavy metal ions. Different resin dosages, contact time, and initial concentrations were used, and the batch technique experiment was utilized. The study also applied the Langmuir and Freundlich isotherm model, and Langmuir was found to be better. The absorption ability was found to be better for polyamidoxime resin for metal ions of cadmium (II), chromium (III), and lead (II).

“…Common techniques employed for silver extraction include chemical precipitation, 6,7 membrane filtration, 8 ion exchange, 9 electrochemical treatment, 10,11 solid phase extraction/adsorption, 12,13 and liquid-liquid extraction. [14][15][16][17] Liquid-liquid extraction has found wide application due to the ability of the extractants to form stable complexes with the silver ion, 18 resulting in efficient extraction and ease of operation.…”

Ligands bearing S-and N-donors are an important class of extractants with demonstrated efficiency and selectivity for Ag + extraction over metals with similar chemistries. However, the synthesis of some of these ligands can be complicated and low yielding. Here, we report the synthesis of a novel ligand -N-(2-((4vinylbenzyl)thio)ethyl)acetamide, over two simple steps and in a good yield. The extractant was observed to demonstrate excellent selectivity for Ag + , extracting only Ag + from an aqueous solution also containing Cu 2+ and Pb 2+ .Moderate extraction efficiencies of 36 % for Ag + and 0% each for Cu 2+ and Pb 2+ were observed. From mass spectrometry and proton NMR titration data, the extractant was found to form both the 1:1 and 1:2 (Ag + :ligand) complexes with Ag + indicating that ligand forms bent linear and tetrahedral coordination complexes with Ag + . Overall, the results indicate that the novel amide-based ligand is highly selective for Ag + removal from aqueous solutions containing Cu 2+ and Pb 2+ . These results indicate the ligand could be easily synthesized and applied for selective silver recovery from low grade ores.
