Adsorbents for the purification and recovery of biocompounds: An updated review

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.
