SEPARATION AND PURIFICATION REVIEWS, 2024 (SCI-Expanded)
Adsorption, a crucial method for removing dyes from wastewater, has been extensively studied in the context of eliminating Acridine Orange (AO), a cationic dye, from contaminated water. This review underscores the environmental risks posed by AO, given its high toxicity, and delves into various adsorption techniques developed to eliminate it from water. It covers works on AO removal published from 1981 to April 2024, highlighting the effectiveness of different adsorbents, including natural, synthetic, composite, and nanomaterials, under varying conditions like pH, initial dye concentrations, temperature, and adsorbent dosages. Most studies on adsorption isotherms, kinetics, and thermodynamics have yielded favorable results, with common models including the Langmuir and Freundlich and pseudosecondorder kinetics. As identified by these studies, the main driving force for adsorption is electrostatic interactions between AO and the adsorbents. The review also encompasses competitive adsorption, adsorbent regeneration, alternative decontamination methods, and the pivotal role of computational research in optimizing adsorption processes.
