is expected to be a good candidate plant for desert reclamation ("greening") since it has notable tolerance to cold and drought and can grow in a wide range of areas with different soil types and moisture contents. In this study, we have developed a single-step method to fabricate a cellulose acetate (CA)/ shell (APS)-derived activated carbon (AC) composite monolith by thermally induced phase separation (TIPS) for removal of toxic phenol from aqueous solution. The composite monolith was easily fabricated by TIPS of a CA solution in the presence of the dispersed AC, in which AC was well loaded onto the monolithic skeleton of CA. The as-obtained monolith showed a maximum adsorption capacity of 45 mg g at the initial phenol concentration of 0.8 mg mL. The present composite can be prepared with an arbitrary shape by a facile method from cheap materials, and is more convenient to recycle than powder adsorbents. Therefore, the present CA/APS-derived AC composite monolith has great potential as a promising adsorbent of low cost with convenient separation for toxic phenol-containing wastewater.
由于它对寒冷和干旱具有显著的耐受性，并且能够在具有不同土壤类型和含水量的广泛区域生长，因此有望成为沙漠开垦（“绿化”）的优良候选植物。在本研究中，我们开发了一种单步方法，通过热致相分离（TIPS）制备醋酸纤维素（CA）/壳聚糖（APS）衍生的活性炭（AC）复合整体材料，用于从水溶液中去除有毒苯酚。在分散的AC存在下，通过CA溶液的TIPS可以轻松制备复合整体材料，其中AC被良好地负载到CA的整体骨架上。在初始苯酚浓度为0.8 mg/mL时，所获得的整体材料显示出最大吸附容量为45 mg/g。本复合材料可以通过简便的方法由廉价材料制备成任意形状，并且比粉末吸附剂更便于回收利用。因此，本CA/APS衍生的AC复合整体材料作为一种低成本且分离方便的有前途的含毒苯酚废水吸附剂具有巨大潜力。
