Electrospun composites nanofibers from cellulose acetate/carbon black as efficient adsorbents for heavy and light machine oil from aquatic environment

Abstract The feasibility of preparing cellulose acetate/carbon black (CA/CB) composite nanofiber in one step through electrospinning process and investigating its potential oil absorbability application for machine removal from aquatic environment was reported. Different CA/CB nanofibers were fabricated by acetate (CA) solution containing different loads 0.7, 1.5, 2.2% CB relative to the weight CA labeled as CA/CB0.7, CA/CB1.5, CA/CB2.2. scanning electron microscope (SEM) images showed continuous smooth fiber with submicron diameter ranging 400–900 nm good adhering into nanofiber. Furthermore, exhibited high surface area compared nanofiber, which reached 3.057, 2.8718 8.244 m 2 /g CA/CB1.5 CA/CB2.2, respectively. Oil adsorption tests performed heavy light oils. higher affinity an aqueous than pure has exceptional performance both oils, maximum adsorbed 10.6 18.3 g/g kinetic oils fitted well pseudo-second-order model. Besides, exposed properties respectable reusability after regeneration four consecutive cycles. results advocate excellent as-fabricated a promising reusable adsorbent spill cleanup applications.
