Effect of Spinning Process on the Absorption Performance of Wooden Activated Carbon Fiber for Methylene Blue

Abstract:

In order to improve the adsorption performance of wooden activated carbon fibers (WACFs) and enlarge its application in food safety and fresh, the charcoal dust is used as pore-forming agent, and the absorption performance of WACFs for methylene blue (MB) by changing the liquid-solid rate, charcoal content, synthetics content and hydrochloric acid concentration is studied. The results show that: with the increase of liquid-solid ratio, the absorption capacity of WACFs for MB increases accordingly; with the increase of charcoal content and synthetics content, the absorption capacity both show the tendency of increasing first then reducing after accordingly, with the maximum absorption capacities of 534.61mg·g^-1 and 527.25mg·g^-1 respectively reached by 1% charcoal content and 4% synthetic content. When the hydrochloric acid concentration was below 15%, the absorption capacity increases linearly, while reduced when hydrochloric acid concentration was over 15%.
