Fabrication of PCL/CMARX/GO Composite Nanofibrous Mats for Dye Adsorption: Wastewater Treatment

The effluents of industrial wastewater contain several toxic organic and inorganic pollutants that may contaminate clean freshwater sources if untreated or poorly treated. These include colors; hazardous compounds; surfactants; cosmetics; agrochemicals; pharmaceutical by-products; agricultural, pharmaceutical, medical contaminants. Treating has become a global problem. Many projects have been started in the last two decades to treat wastewater, resultant water pollution, associated waste management problems. Adsorbants based on graphene oxide (GO) are viable treatment materials due their adaptability, photocatalytic action, capacity for self-assembly. Here, we report fabrication nanofibrous mats from polycaprolactone (PCL), carboxymethyl arabinoxylan (CMARX), carboxyl-functionalized-graphene using an electrospinning technique. silver nanoparticles were loaded onto mat enhance activity. characterized different techniques, including Fourier transform infrared (FTIR), scanning electron microscope (SEM), transmission (TEM). contact angles used study hydrophilic hydrophobic behavior. Langmuir isotherm model adsorption kinetics studied evaluate capabilities against methylene blue (MB). Sample 2 followed (R2 = 0.9939). Adsorption exhibited pseudo-second order behavior 0.9978) maximum correlation coefficient values. MB excellent at room temperature formation monolayer surface mat. An enhanced PO43− was observed, providing recyclability up 4–5 times. Hence, fabricated would be potential candidate more effective applications.
