摘要

为了研究电化学再生活性炭纤维（ACF）的效果，以SCN-为模型物，通过测量再生后活性炭纤维对SCN-的吸附容量的大小，考察了时间、吸附质浓度、再生循环次数等再生过程中的影响因素。结果表明，适宜的再生条件为0.8 mA正极化2 h，0.5 mol·L-1的硫酸溶液，能使再生后ACF的吸附容量提高为原始ACF的3倍。5次电化学再生循环后，ACF的吸附容量没有明显降低，再生后ACF纤维表面也没有明显损伤。

Abstract

The effectiveness of electrochemical regeneration of active carbon fiber (ACF) loaded with SCN-

was assessed by adsorption capacity of regenerated ACF achieved in the re-adsorption experiment. The influences of regeneration parameters such as regeneration time

adsorbate concentration and regeneration circle times were investigated. Adsorption capacity of regenerated ACF could reach 3 times of fresh ACF

under the optimum conditions 0.8 mA in 0.5 mol·L-1 H2SO4 solution for 2 h. No significant declination of ACF adsorption capacity was observed after five-times continuous adsorption-regeneration cycles

and no significant damage occurred on the surface of ACF after regeneration.
