“…Both anionic and non-ionic surfactants deliver harmful effects due to acute toxicity. However, the non-ionic ones display higher toxicity as compared to their anionic counterparts [25]. The use of surfactants has been a usual practice and has seen a rise from the 1980s, emerging from 1.7 million tons in 1984 and 9.3 million tons in 1995 [166] to a massive 15.93 million tons in 2014 and a probable figure of 24.19 to be used in 2022 [26].…”

Adsorption has widespread applications in separation processes, particularly aiming at environmental decontamination owing to its economic and highly efficient outcomes. This literature studies various isotherm models concerning adsorption which is accompanied by information related to the mechanism of the adsorption process, which is a crucial aspect of the system design. Many modification techniques bring about a significant enhancement in the working capacity. The build‐up of industrial activities causes a spike in the dispersion of toxic compounds along with non‐biodegradable contaminants from industrial wastewater. The separation techniques have emerged with greater efficiency in eliminating specific pollutants in terms of discharge legislation. Such methods have been reviewed hereby in this document based on literature published lately. Concerning the process of adsorption, this review elucidates the adsorption isotherms, kinetic models, breakthrough curve modelling, thermodynamic concepts, and the regeneration of the support required in batch or continuous reactors.

“…Various surfactants such as polymers, biopolymers, and organic linkers were employed to synthesize targeted porous architectures. [30] During preparation, metal precursors form a weak non-covalent bond (hydrogen bonds, van der Waals forces, and electrostatic interaction) with the surfactant to give a self-accumulated micelle. The approach is also known as the sol-gel process, [31] as the micelle results in a gelatinous slurry.…”

Intrinsic structural characteristics of porous materials have found significant applications in selective separation of gases and heterogeneous catalysis. While using porous materials for gas separation and catalysis, some of the challenging issues are the strength of catalytic sites, hydrothermal stability, crystalline order of solids, and selectivity. Researchers' ability to engineer the synthesis strategies rationally can help overcome technological challenges. In recent years, breakthroughs in porous materials are focused on developing different chemistries to control the pore architecture. This review focuses on recent advances made in synthesis strategies of porous materials and their impact on gas separation and catalysis applications. A significant part of this review is devoted to various synthesis methods, such as various types of templating methods, molecular layer deposition, sol-gel technique, and polymerization methods. Improvement in various catalytic reactions and gas separations due to different functionalization methods is also summarized. Lastly, we have discussed the applications of porous materials in the form of adsorbents and membranes in commercial processes. We hope that this review will serve as a quick reference for beginners who want to synthesize porous materials with control of pore structure.

“…The characteristics of various adsorbents and the adsorption mechanisms involved have been reported (Siyal et al 2020). Moreover, application of biopolymers as a new age sustainable material for surfactants adsorption and the impact of surfactants on wastewater treatment processes and emerging treatment technologies have been summarized (Biswas and Pal 2021;Palmer and Hatley 2018). Shreya et al (2021) have reviewed the removal of surfactants from greywater using original and/or modified forms of low-cost waste materials.…”

Wastewater treatment has an important responsibility to react to changing consumer and industrial-produced wastes that pose environmental challenges. Surfactants are one of these emerging contaminants. They are of interest because of their increasingly ubiquitous domestic and industrial use and the difficulty their presence causes traditional treatment. Compared with other treatment technologies, adsorption is a promising approach due to its low cost and environmental friendliness. This paper reviews the hazards of surfactants, the removal effect and mechanism of surfactants by conventional activated carbon, mineral materials, Chitosan-based materials, carbon materials and agricultural waste, and also summarizes the classification of adsorbent regeneration. Finally, future perspectives on surfactants removal and exploitation of adsorbent are presented. Through a comprehensive review, we expect that this review will help the reader to more rationally select the appropriate adsorbent based on the removal mechanism.
