Paper Title:
The Preparation of the Second Modification of Activated Carbon Fiber Loaded Mn
  Abstract

The Mn loaded ACF (ACF-Mn), prepared by impregnation method combined with activation method under high temperature, can be second modified. The best second modifiers, modifier concentration and activation time condition for ACF-Mn was determine by orthogonal experiments. The modified ACF was characterized by XRD、SEM、EDS and other ways. The results show that the optimal conditions for the second modification was that at 700°C under the protection of N2 activation for 50 min when the modifier concentration of CuSO4 was 10%. The iodine adsorption value of the second modified ACF is 1605.36 mgg-1, and the content of basic functional groups is 119.86 mmolg-1. The granular Cu, Mn attached to the surface of ACF and significantly increased its crystallinity. This is helpful to increase the surface area and enhance its adsorption properties.
