Abstract

High quantities of synthetic dyes are prevalent in wastewater, which are disposed into the environment without proper treatment. In this work, two types of aluminum based metal-organic frameworks, Al-FA (fumaric acid) and Al-SA (succinic acid), were synthesized using water as the solvent and employed for the adsorption of mono and di-azo dyes. Al-SA exhibited superior affinities towards both substrates compared to those of Al-FA, with maximum adsorption capacities of 559.28 and 332.48. mg/g for mono and di-azo dyes, respectively. Overall findings insinuate that Al-SA can be considered as a promising candidate for efficient azo dye removing agent.
