Abstract
In this study, we developed simple process for ethanol concentration. We developed magnetically separable polyanilline nanofiber (PAMP) for selective ethanol adsorption. PAMP can adsorbed 80% of ethanol in the solution. After adsorption, the ethanol was recovered with simple magnetic separation and centrifugation process. After 10 times recycle of PAMP, the ethanol adsorption maintained 92% of its initial adsorption capacity. Using ethanol concentration process, the ethanol concentration increased up to 197.6 g/L from 46 g/L which was 4.3 folds increase.
