Metal−Organic frameworks (MOFs) have emerged as an extensive class of crystalline materials with ultrahigh porosity (up to 90% free volume) and enormous internal surface areas, extending beyond 6000 m²/g. These properties, together with the extraordinary degree of variability for both the organic and inorganic components of their structures, make MOFs to be interested for potential applications. In this work MOF based on copper was applied to the adsorption of methylene blue (MB) from aqueous solution. It was found that the Cu-BTC adsorption capacities of MB are much higher than those of the other types of MOFs and adsorbents. Two simplified kinetic models including pseudo-first-order, pseudo-second-order, were used to investigate the adsorption process. The pseudo-second-order equation was followed for adsorption of MB on Cu-BTC.
