Electrocentrifugal spinning (ECS) has emerged as a promising alternative to conventional electrospinning for fabricating high-performance nanofibers, addressing key limitations such as high-voltage requirements and low production rates. In this study, polyacrylonitrile (PAN) nanofibers were synthesized via ECS and systematically compared with electrospun fibers in terms of morphology, production efficiency, and adsorption performance. ECS produced fibers with 40% smaller diameters (225–316 nm), a 33% higher dye adsorption capacity, and a 68% increase in production rate. Adsorption kinetics for Reactive Blue 13 followed a pseudo-second-order model (R² = 0.98), indicating chemisorption, while isotherm data fit the Langmuir model (qm = 96.15 mg/g, R² = 0.99). ECS achieved superior dye removal efficiency (90%) compared to electrospinning (72%) and forcespinning (82%). These results demonstrate that ECS is a scalable and economically viable method for mass-producing high-efficiency nanofibers, with significant potential for industrial wastewater treatment applications.
