摘要：
Polyacrylonitrile (PAN) hollow fibers were pretreated with ammonium dibasic phosphate, then further oxidized in air, carbonized in nitrogen and activated with carbon dioxide. Then the surface of resultant PAN activated carbon hollow fiber (PAN-ACHF) was coated with polyvinyl alcohol aqueous solution of different concentration. The effects of PVA concentration on specific surface area and adsorption properties were studied in this work. After the coating process, the specific surface area of PAN-ACBF significantly decreases with PVA concentration increasing. Moreover, with PVA concentration increasing, the number and size of pores on the external surface of PAN-ACBF significantly decrease, and the adsorption ratio of PAN-ACBF to creatinine almost does not change, but that to VB12 markedly decreases.
