“…The use of various non-toxic adsorbents has proven to be a successful approach for the simultaneous removal of multiple heavy metals, metalloids, and other pollutants from polluted water and wastewater. This method is highly effective, practical, economical, and environmentally friendly [39,257]. To achieve optimal results, mathematical tools [258], such as machine learning algorithms [259], can be employed to assess and optimize the adsorption processes' isotherms, thermodynamics, kinetics, and operational parameters.…”

Heavy metal contamination in wastewater is a significant concern for human health and the environment, prompting increased efforts to develop efficient and sustainable removal methods. Despite significant efforts in the last few decades, further research initiatives remain vital to comprehensively address the long-term performance and practical scalability of various adsorption methods and adsorbents for heavy metal remediation. This article aims to provide an overview of the mechanisms, kinetics, and applications of diverse adsorbents in remediating heavy metal-contaminated effluents. Physical and chemical processes, including ion exchange, complexation, electrostatic attraction, and surface precipitation, play essential roles in heavy metal adsorption. The kinetics of adsorption, influenced by factors such as contact time, temperature, and concentration, directly impact the rate and effectiveness of metal removal. This review presents an exhaustive analysis of the various adsorbents, categorized as activated carbon, biological adsorbents, agricultural waste-based materials, and nanomaterials, which possess distinct advantages and disadvantages that are linked to their surface area, porosity, surface chemistry, and metal ion concentration. To overcome challenges posed by heavy metal contamination, additional research is necessary to optimize adsorbent performance, explore novel materials, and devise cost-effective and sustainable solutions. This comprehensive overview of adsorption mechanisms, kinetics, and diverse adsorbents lays the foundation for further research and innovation in designing optimized adsorption systems and discovering new materials for sustainable heavy metal remediation in wastewater.

“…The XPS C1s spectrum was deconvoluted into six distinguished peaks at 284.2, 258.9, 287.5, 289.2, 290.7, and 292.5 eV. These peaks are associated with C sp 2 , C sp 3 , and carbon bound to oxygen (C-O) in esters or phenol structures, the double bond between carbon and oxygen (C=O) in quinones and ketones, two oxygen atoms in carboxylic acid, carboxyl, or esters (-COO), and carbonates, respectively [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]. It is interesting to point out that the carbonaceous materials derived from sucrose (C-meso and CN-meso) present a smaller ratio between Csp 3 and Csp 2 than CN-meso Chit and CN-meso Gluc.…”

Selective oxidation, which is crucial in diverse chemical industries, transforms harmful chemicals into valuable compounds. Heterogeneous sonocatalysis, an emerging sustainable approach, urges in-depth exploration. In this work, we investigated N-doped or non-doped carbonaceous materials as alternatives to scarce, economically sensitive metal-based catalysts. Having synthesized diverse carbons using a hard-template technique, we subjected them to sonication at frequencies of 22, 100, 500, and 800 kHz with a 50% amplitude. Sonochemical reaction catalytic tests considerably increased the catalytic activity of C-meso (non-doped mesoporous carbon material). The scavenger test showed a radical formation when this catalyst was used. N-doped carbons did not show adequate and consistent sonoactivity for the selective oxidation of 4-Hydroxy-3,5 dimethoxybenzyl alcohol in comparison with control conditions without sonication, which might be associated with an acid–base interaction between the catalysts and the substrate and sonoactivity prohibition by piridinic nitrogen in N-doped catalysts.
