Synthesis of porous iron – zirconium mixed oxide fabricated ethylene diamine composite for removal of cationic dye

Abstract

Synthesis of iron-zirconium binary oxide fabricated ethylene diamine (IZBO-en) composite involved two step synthesis including mixed binary oxide synthesis followed by synthesis of binary oxide-ethylene diamine composite. Mixed binary oxide was synthesized by co-precipitation method using ammonia as neutralizing agent. Binary oxide based ethylene diamine composite was synthesized using sodium dodecyl sulfate and potassium persulfate as reagents in reaction. Yield of product was 88%. Characterization of the material was done using Fourier-transform infrared spectroscopy, scanning electron microscopy, and Brunauer-Emmett-Teller analysis. Surface area was found to be 54.74 m 2 g-1. The synthesized material was efficient for removal of cationic dye methylene blue which is known for its toxicological effects. Adsorption parameters like contact time, dose, interference and pH were studied. Maximum adsorption capacity was found to be 242.79 mg g-1. Kinetic data suggested the mechanism of adsorption follows pseudo-second-order rate (R 2 = 0.998) with a rate constant of 2.788 mg g-1 min-1 and follows Langmuir adsorption isotherm model (R 2 = 0.987). Thermodynamic study revealed the process to be spontaneous and feasible with large negative free energy (ΔG =-9.54 kJ mol-1). Column study shows a removal of 600 ml 2 mg L-1 with 1 g material. Desorption was achieved with 79% regeneration in acidic medium. Real wastewater from nearby textile industry was tested and found to get decolourized with the material. In conclusion, IZBO-en can be efficiently used in detoxification of cationic dyes.
