“…Although both physical and chemical attachment mechanisms are employed, the strength and selectivity of the latter are superior [75]. Activated carbon has been extensively used for critical metals extraction from wastewater [76][77][78][79][80], as well as in capturing Au and Ag ions from solutions [81][82][83][84][85][86] and water purification [87][88][89].…”

Notable increases in metal consumption and declining ore grades in recent decades have stressed the significance of dilute solutions as secondary sources of valuable metals. Moreover, environmental considerations and the imperative of sustainable development have further emphasized their treatment. Therefore, finding an efficient solution for separating metals from dilute solutions has attracted the attention of numerous researchers. This paper reviews the purification processes of dilute solutions and highlights key achievements of published research works. Although this study focuses on evaluating the efficiency of recently developed aqueous-phase purification methods, such as immobilized ligands, ionic liquids, and air-assisted solvent extraction, the application of conventional processes to treat these solutions, such as solvent extraction, ion exchange, membranes, chemical precipitation, and adsorption are also briefly outlined. To provide a comprehensive assessment, more than 200 research articles were reviewed, and their key findings are stated in this study. This research contributes to the advancement of knowledge of metal recovery from dilute solutions and sheds light on the dynamic evolution of this field.

“…This validates that the AC is an excellent absorbent owing to its characteristics such as large surface area and the presence of functional groups such as quinone, carbonyl, lactone, phenol, and carboxyl. 52,53 It was reported that AC surfaces with large mesoporous areas exhibit relatively high adsorption capacity for some metal ions like Pd and Cd. 54 The adsorption process could have been possible through ion exchange, acid−base, complexing metal ion, or surface precipitation of the AC surface and metal ions present in the wastewater.…”

The presence of metal ions in an aqueous medium is an ongoing challenge throughout the world. Processes employed for metal ion removal are developed continuously with the integration of these processes taking center stage. Herein, an integrated system consisting of flocculation, activated carbon (AC), and an ultrafiltration (UF) membrane was assessed for the removal of multiple metal ions contained in wastewater generated from a university chemistry research laboratory. The quality of the wastewater was established before and further determined after treatment with inductively coupled plasma optical emission spectrometry (ICP-OES) for metal content, total dissolved solids (TDS), turbidity, electrical conductivity (EC), and pH. Assessing the spent AC indicated minimal structural changes, indicating a potential for further reuse; for instance, the BET for both the pristine and spent AC exhibited type I isotherms with a mesoporous structure, indicating no major structural changes due to metal complexation. The relative performance of the integrated system indicated that the use of flocculation improved the water quality of metal-laden wastewater for safe disposal. The integrated treatment systems exhibited high removal efficiencies between 80 and 99.99% for all the metal ions except for Mn (<0.008 mg L–1) and Cr (<0.016 mg L–1) both at ca. 70%, indicative of the positive influence of the polyelectrolyte in the treatment process. The fabricated UiO-66-NH2@GO membranes (Z4 and Z5) exhibited high fouling resistance and reusability potential as well as relatively high pure water flux. Consequently, the integrated process employed for the treatment of laboratory metal-containing wastewater is promising as a generic approach to improving the quality of metal-containing wastewater to meet the standards of discharging limits in South Africa.

“…[14] S. Kocaoba has also treated water against lead by using IRA 120 resin and got a removal efficiency of more than 95%, this study investigated the removal of lead (Pb) and cadmium (Cd) metal ions from aqueous solutions, focusing on various parameters such as pH, adsorbent amount, contact time, and concentration, optimal conditions for this process were determined to be a metal ion concentration of 20 mg/L, pH of 5, a contact time of 60 minutes, and an adsorbent amount of 0.5 g. The adsorption behavior was wellsupported by Freundlich and Langmuir isotherms, with the adsorption coefficients indicating favorable adsorption. [15] In this study use of activated carbon derived from Turkish pine cones as a highly effective adsorbent for removing metal ions, specifically zinc (Zn). Turkish pine cones are considered a promising commercial source of activated carbon due to their strong adsorption capacity, rapid metal removal, and excellent regeneration capabilities.…”

Everyone needs access to hygienic water to live a healthy life. Despite being complex, the connection between the water environment and human activities has been thoroughly demonstrated over the past few decades through various study methods. Among the numerous pollutants that contaminate water, zinc is particularly harmful to humans and the environment, including soil and water bodies. The assessment and removal of zinc from water sources are of utmost importance. This paper examines and removes zinc using the ion exchange resin Amberlite IRA-120. The advantage of this resin is that it can be recycled and reused without compromising the quality of water treatment, making it both economical and readily available. The batch experiment is performed at different pH levels, concentrations, and competing ions. under constant conditions to achieve maximum zinc removal at optimum conditions. The regenerated resin is then employed for subsequent removal cycles, demonstrating that the fifth application attains an efficiency of 75%. In the fixed bed column study, it treated more than 6ml/mm3 of water against zinc. Regeneration of resin is done by regenerating solutions. Resin shows high selectivity to zinc while other metal ions are mixed in the zinc solution. The maximum uptake capacity of this resin is determined at lower pH i.e. 4.5, further study is being done on pH 7 because the study is mainly focused on drinking water. This indicates that even after multiple uses, the upgraded system maintains water quality, allowing for the reuse of treated wastewater.
