Effect of Concentration on Electrospinning Oil Sorptive Fiber
Electrospinning is a convenient method used in the preparation of ultrafine oil sorptive fibers based on Ethylene-propylene-diene (EPDM), Electrospun fiber diameter, varying in large from micrometer to nanometer, mainly depends upon the solution concentration, which has great influence on this function fiber’s sorption ability. The non-linear relation between mean fiber diameter (d) and solution concentration (C) was investigated and it follows a simple scaling law in the form . This relationship can be used to predict the target fiber diameter and guide the processing technique. The effects of various C on oil sorption ability were investigated in a batch-sorption technique. A comparison of the kinetic models, showed that the removal rate fit the first order kinetic model well, which suggested the sorption process is rapid, can reach equilibrium within a short time.
