“…[8][9][10][11] Adsorption is the most promising strategy to enable the capture of emerging contaminants. [12][13][14] Among the new sorbents emerging in the literature for water applications, graphene oxide (GO) is particularly advantageous as a sorbent. It can be exploited as a standalone material [15][16][17][18][19] or as an additive of polymeric membranes, in order to develop adsorptive membranes (i.e.…”

Recently, the development of techniques to produce detoxified biocompounds has attracted much research interest. This study reviews adsorbents for application in the purification and detoxification of biocompounds, aiming to identify the field's knowledge gaps, trends, updates and hotspots. This review focuses on the description of the types of adsorbents (activated carbon, zeolites, clays, clay minerals and biosorbents) and their activation methods (chemical and physical) for laboratory and industrial adsorption. The adsorbents that stand out are activated carbon and chitosan‐based adsorbents. Moreover, there is a research trend toward using adsorbents to purify bioactive compounds, sugars and amino acids. Finally, adsorbents underscore a growing global research interest in exploring effective treatments for removing various combinations.

BACKGROUNDDeveloping robust technologies to remove emerging pollutants from water is urgent since conventional treatments are not technically prepared to remove them. This paper investigated the ibuprofen (IBU) adsorption capacity onto natural zeolite (NZ) and hydrothermally modified zeolite in an acidic medium followed by impregnation with the cationic surfactant cetyltrimethylammonium bromide (CTAB) (MZHT‐CTAB). The materials characterization included scanning electron microscopy (SEM), X‐ray diffraction (XRD), atomic absorption spectroscopy (AAS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA/DTG), N2 adsorption/desorption isotherm (BET), Zeta Potential (ZP), and Point of Zero Charge (pHPZC). The adsorptive capacity studies were carried out by varying the pH solution, a kinetic study at three concentrations (25, 50, and 100 mg L−1), and the contaminant concentration influence (5–100 mg L−1).RESULTSThe results showed that the MZHT‐CTAB obtained both the highest removal efficiency (~ 37%) and the highest adsorption capacity (~ 14 mg g−1) at pH 5.0. The Pseudo Second‐Order (PSO) model, which showed the best fit to the experimental data, is significant as it indicates the reliability of our results. The maximum adsorption capacity for the concentration of 100 mg L−1 was 11.93 mg g−1. According to Giles's classification, the isotherm was classified as S‐3 type, indicating the competition between the adsorbate and water molecules for the active sites on the adsorbent surface.CONCLUSIONThe adsorption studies demonstrate that the novel adsorbent (MZHT‐CTAB) is highly effective in removing IBU, presenting a significant removal capacity and feasibility. This promising result contributes to the ongoing search for alternative materials for water treatment. © 2024 Society of Chemical Industry (SCI).
