摘要:
为增强二硫化钼(MoS2)对水中Cr(Ⅵ)的去除能力,以D葡萄糖、苯胺为原料合成碳气凝胶(CA),然后采用水热法将二硫化钼(MoS2)负载到CA上制得CA/MoS2复合物,采用扫描电子显微镜(SEM)、X射线衍射(XRD)、拉曼光谱仪、X射线光电子能谱(XPS)和BET对其形貌、晶形和结构进行表征。考察了CA/MoS2复合物对水中Cr(Ⅵ)的去除效果,并探究了pH值、温度、共存离子等因素对CA/MoS2复合物去除Cr(Ⅵ)的影响,结果表明:CA/MoS2具有优异的去除性能和重复使用性,去除Cr(Ⅵ)的容量高达4602 mg/g。此外,XPS对CA/MoS2复合物使用前后分析表明,CA/MoS2先将水中Cr(Ⅵ)吸附至表面,然后利用MoS2原位还原为Cr(Ⅲ),而且大部分Cr(Ⅲ)释放到溶液中。该CA/MoS2复合物制备简单,使用便捷,为有效治理Cr(Ⅵ)废水提供了新方法。
