【Abstract】 The adsorption properties of VACF-P (viscose-based activated carbon fiber activated with phosphoric acid) for organic vapors, and chromium, silver and gold ions in solution were studied. The experimental results showed that VACF-P possesses good adsorption ability for various organic vapors. VACF-P prepared at 350-500℃ or with high concentration of phosphoric acid have an increasing adsorption capacities for polar vapors such as methanol and alcohol. The adsorbed VACFP can be completely regenerated by heating at 128℃ for 20 min. Some VACF-P activated at low temperature has high adsorption capacity for Cr~6+ as high quality ion exchange fibers. VACF-P possess redox ability and the reduction-adsorption capacity for An~3+ can reach 700-1100mg/g.更多还原
