METAL-ORGANIC FRAMEWORKS (MOFs) DERIVED FROM CARBOXYLATE LIGAND AS POTENTIAL MATERIALS FOR REMEDIATION OF Cu (II) AND Pb (II) FROM AQUEOUS SOLUTION
Abstract
The remediation of cadmium and lead ions from their respective aqueous solutions was carried out with the use of metal-organic frameworks (MOFs) developed from copper and zinc with benzene-1,4-dicarboxylic acid (BDC). The experimental adsorption process was done in batches to determine the equilibrium characteristics, thermodynamics and kinetics of the sorption processes. The result was then tested using Langmuir, Freundlich, and Temkin isotherm equations with Langmuir being the best fitted isotherm, while the kinetics isotherm used were pseudo first order and pseudo second order. The result obtained shows that the MOFs are great potential adsorbent for the studied metals.
