摘要: 随着矿物开采规模的不断扩大，尾矿废水已成为全球环境污染的重要来源，尾矿废水中含有大量丁基黄原酸钾等有毒有害的化学物质。在本工作中，通过水热法制备了一种新型3D多孔石墨烯气凝胶(GO-aerogel)吸附材料。结合动力学系统地研究GO-aerogel对浮选尾矿废水中黄原酸盐xanthate (KBX)的吸附性能，吸附动力学符合准二级动力学模型。吸附实验表明该材料吸附模型符合Freundlich，吸附量最大可达到2482.69 mg/g。吸附过程主要是化学吸附，多分子层吸附。研究结果表明，GO-aerogel气凝胶有望作为一种去除尾矿废水中黄原酸盐的良好吸附剂。
Abstract: With the continuous expansion of mineral mining scales, tailings wastewater has become a major source of global environmental pollution. Such wastewater contains substantial amounts of toxic and harmful chemicals such as potassium butyl xanthate. In this work, a novel three‑dimensional porous graphene oxide aerogel (GO‑aerogel) adsorbent was prepared via a hydrothermal method. The adsorption performance of GO‑aerogel for xanthate (KBX) in flotation tailings wastewater was systematically investigated in combination with kinetics. The adsorption kinetics followed a pseudo‑second‑order model. Adsorption experiments showed that the adsorption behavior was well described by the Freundlich isotherm, with a maximum adsorption capacity reaching 2482.69 mg/g. The adsorption process was primarily dominated by chemical adsorption and multilayer adsorption. The results demonstrate that GO‑aerogel holds great potential as an effective adsorbent for the removal of xanthates from tailings wastewater.
