CW18O49可再生吸附剂处理染料废水的研究 生物管理专业

摘要 该研究用水热法制备了多种 C–W18O49纳米复合材料。本实验研究了碳材料的形态结构，温度，和环境条件对合成的 C–W18O49纳米复合材料吸附效果的影响。结果表明 ，600℃碳化两小时后的饼干没经磨碎后放入钨溶液中进行水热合成 C–W18O49复合吸附剂，碳含量充足，结晶度高具有明显晶格，吸附性能较其他样品效果好。在紫外-可见-近红外吸收光谱图中，C–W18O49纳米复合材料显示出强吸收，表明表明碳组分的存在强烈地增强了红外区域的吸收，这可能有利于改善 C–W18O49纳米复合材料的吸附和光催化再生活性。关键词多孔碳材料；氧化钨；染料废水；光催化氧化法；水热法论文题目：C/W18O49可再生吸附剂处理染料废水的研究IAbstract In this study, various C–W18O49 nanocomposites were prepared by hydrothermal method. In this experiment, the effect of the morphological structure, temperature, and environmental conditions of carbon materials on the adsorption of synthesized C–W18O49 nanocomposites was investigated. The results showed that the biscuits after carbonization at 600°C for two hours were ground and put into the tungsten solution to hydrothermally synthesize C–W18O49 composite adsorbent. The carbon content was sufficient, and the crystallinity was high. The crystal lattice had obvious lattice and the adsorption performance was better than other samples. it is good. In the UV-Vis-NIR absorption spectrum, the C–W18O49 nanocomposite shows strong absorption, indicating that the presence of the carbon component strongly enhances the absorption in the infrared region, which may help to improve the C–W18O49 nanocomposite.
