Magnetic nanoparticles, magnetite, are incorporated in functionalized multi-walled carbon nanotubes (f-MWCNTs) to prepare magnetic nanocomposite, which is subsequently used to fabricate buckypaper (BP) with the aid of vacuum filtration technique, to resolve the challenges associated with the developed method for furazolidone treatment. The maximum removal efficiency of 98.74% was achieved at 10 mg/L, pH 6, and a contact time of 350 min. The results showed that equilibrium adsorption data were best-fitted to the Langmuir isotherm model with correlation coefficient of 0.994, and the maximum furazolidone uptake was 29.67 mg/g; moreover, the mechanism of adsorption kinetic data was well defined by a pseudo-second order kinetic models. The thermodynamic parameters (enthalpy, entropy and Gibbs energy) suggested the spontaneous, feasible and exothermic nature of furazolidone adsorption over the magnetic f-MWCNTs-based BP/PVA. Besides, a reusability study was performed using ethanol as a desorption solvent, and results revealed that the magnetic f-MWCNTs-based BP/PVA can remove up to 88% of furazolidone removal efficiency even after five successive cycles. Thus, the research study concluded that the fabricated magnetic f-MWCNTs-based BP/PVA membrane could efficiently remove furazolidone micropollutant without any additional separation stage, subsequently, could be utilized as an efficient membrane for practical applications.
Highlights
Project Description: This research aims to develop an innovative membrane that has the characteristics of magnetic functional-multi-wall carbon nanotubes and buckypaper to be utilized for micropollutants removal from the aqueous phase without the use of an external magnetic field for separation. Problem Statement: The mutagenic and carcinogenic properties of emerging micropollutants, especially in the farming and aquaculture industry which used steroid hormone, particularly furazolidone has been detected in wastewater effluent. Furazolidone is currently prohibited by the Food and Drug Administration and no longer available in the US and some developed countries. Many compounds can be treated through conventional methods, but not for micropollutants. Magnetic nanoparticles incorporated in multi-wall carbon nanotubes have attained significant interest from many researchers, especially in water remediation. Nevertheless, it is restricted to commercialization due to an external magnetic field requirement and particles are not completely separated. In contrast, the buckypaper membrane applications are limited due to low mechanical strength; however, the buckypaper membranes have demonstrated high adsorption capability towards various pollutants in wastewater effluent. Novelty & Invention: 1. Development of a novel membrane that has high efficiency in terms of adsorption of micropollutants. 2. Not require any additional separation stage like magnetic-CNTs nano adsorbents material. 3. Ease the separation or removal of membrane from the wastewater effluent in a continuous process. 4. The property of membrane reusability will further enhance the usage of the membrane in wastewater treatment. Commercial Potential: 1. Comparable wastewater treatment with the conventional method. 2. Easier and better membrane recovery. 3. Reduce energy consumption. 4. Great reusability.
