The MOF synthesized was used for adsorption of sunset yellow and coomasie brilliant blue g250 from aqueous solutions. These dyes are the pollutants obtained from household as well as textile industry. They are found to be anionic in nature as they have SO3- functional groups and are found to have low pKa values and, hence, will exist in aqueous solution as anionic and thus the operation of pH was maintained from 3 to 7 because beyond pH of 8 the MOF was found to be unstable as the carboxylate groups present in the linker got dissociated.
Preliminary adsorption studies were performed and it was found that the MOF was quite significantly removing the dyes from the aqueous stream but was found to take 3 days to equilibrate, thus, it was planned to alter the linker to improve the adsorption kinetics by adding functional groups.
