摘要：

Removal of volatile organic compound (chloroform) from water was carried out by membrane gas stripping using electro-spun poly(vinylidene fluoride) (PVDF) nanofiber membrane. It was shown that the process was feasible. The overall mass transfer coefficient of chloroform through the nanofiber membrane was found to be 2 x 10(-5) m/s at room temperature, which was more than the highest value obtained earlier for a hollow fiber air-stripping system. The activation energy of the mass transfer coefficient was almost the same as that of the Henry constant for chloroform absorption in water. It was therefore concluded that the chloroform desorption from water was the governing factor of the system. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
