“…The saturated adsorbent of CS@Ca@CTA was regenerated with 10 mL of 0.2 mol/L NaOH and 0.2 mol/L NaCl at 25°C to desorb SDBS, and the adsorption capacity remained above 80% after 6 cycles (Wang et al 2019a). For the regeneration of CTAB-zeolite, the desorption rate of SDS increased with the increasing concentration of Na + , indicating that the reduction of SDS ionization weakened the electrostatic interaction with CTAB (Leng et al 2016).…”

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.
