The copper complex-based mesoporous material as an efficient, cost-effective, environment friendly sustainable adsorbent for wastewater pollutants
A transition metal complex-based silica supported organic/inorganic hybrid material was prepared for adsorbing toxic cationic carcinogenic dyes, such as malachite green, from water solutions. The hybrid material was synthesized by using a mixed ligand copper (׀׀) complex having 2,9-dimethyl-1,10-phe...

| description | A transition metal complex-based silica supported organic/inorganic hybrid material was prepared for adsorbing toxic cationic carcinogenic dyes, such as malachite green, from water solutions. The hybrid material was synthesized by using a mixed ligand copper (׀׀) complex having 2,9-dimethyl-1,10-phenanthroline and nitrate, immobilized onto acid functionalized silica support. Extensive characterization utilizing various methods, including Nuclear Magnetic Resonance, X-Ray Diffraction, Inductively Coupled Plasma Spectroscopy, Surface Area measurement, Fourier Transform Infrared Spectroscopy etc. confirmed the phase integrity, the presence of external moieties, material morphology etc. The post-synthetic impregnation method was employed for immobilization of the metal complex onto the porous support. Several parameters which may influence the adsorption process, including pH, adsorbent dosage, NaCl concentration temperature, and contact time were examined and optimal dye adsorption was observed at an adsorbent dosage of 0.25 mg/ml, dye concentration of 10 ppm, pH of 6–7, temperature of 25 °C, and contact time of 5 min. The adsorption of malachite green by copper complex-integrated mesoporous silica proved highly effective, achieving over 99 % adsorption within 5 min. The prepared cost-effective material is recyclable up to four cycles without substantial reduction in adsorption efficiency. We have developed an ordered mesoporous material modified with a transition metal complex that can serve as an inexpensive and eco-friendly adsorbent within exceptionally short contact times underscoring the uniqueness and usefulness of the prepared adsorbent. |
