摘要/Abstract

摘要： 为了对有机物吸附饱和的活性炭纤维(ACF)进行电化学再生研究,以含油废水为模拟有机物,通过测量再生前后ACF对含油废水的吸附效果,考察了电流密度、再生时间、pH值、电解质的电化学再生的影响因素,并研究了电化学再生过程对ACF结构的影响以及ACF电化学再生的机理。结果表明,在电流密度为30 mA·cm^-2,pH值为4,15 g·L^-1 NaCl的溶液中再生120 min,再生率可达到90%,5次电化学再生循环后,ACF保持较高的吸附容量。再生后ACF的表面没有明显损伤,比表面积也没有明显减小,微孔孔径分布于0.5～1.0 nm。由紫外光谱分析可知,ACF的电化学再生机理主要包括电脱附及电化学氧化过程。

Abstract: The effectiveness of electrochemical regeneration of activated carbon fiber(ACF)saturated with oily organic wastewater was assessed by adsorption capacity of regenerated ACF achieved in the re-adsorption experiment.The effects of current density,regeneration time,pH value,electrolyte,and structure of ACF were investigated.The regeneration efficiency can reach 90% under such optimum conditions as current density 30 mA·cm^-2,pH 4,15 g·L^-1 NaCl,and 120 min of regeneration time,and ACFs keep high adsorption capacity after five cycles for continuous adsorption and regeneration.The micropore size distribution of the regenerated ACF is in the range from 0.5 to 1.0 nm.It is not found significant damage on the surface of the regenerated ACF or obvious decrease of its BET surface area.The UV spectra show that the electrochemical regeneration process is mainly due to the desorption and decomposition of organics generated by electrochemical oxidation.
