Adsorption of organic pollutants by metal–organic frameworks

Abstract

This review evaluates the effectiveness of metal–organic frameworks (MOFs) in adsorption organic pollution. MOFs are highly effec-tive in dye effluent removal due to their multifunctionality, water stability, and recyclability. They offer exceptional dye removal and degradation capabilities, with significant surface area and adjustable pore size. Among various dye removal techniques (chemical, physical, and biological), adsorption has emerged as a cost-effective and highly efficient method. Characterization studies confirm the effectiveness of MOFs. Conventional adsorbents fall short of industrial dye removal, thus making MOFs a promising alternative. This review assesses MOFs’ efficacy in treating dyewastewater, highlighting their superior adsorption capacity over conventional materials. Research into inexpensive and efficient adsorbents from available resources for colour removal is increasingly vital. Studies demonstrate the efficacy of numerous affordable adsorbents in colour removal.
