Description

technical field [0001] The invention belongs to the technical field of carbon nanotube adsorption, and in particular relates to a device and a method for improving the efficiency of carbon nanotube adsorption of organic matter. Background technique [0002] In recent years, carbon nanotubes, as a new type of carbon material, have received widespread attention because of their unique one-dimensional tubular microstructure characteristics. The multi-walled carbon nanotubes prepared by catalytic cracking method make it have excellent adsorption performance. The research found that carbon nanotubes The tube has the characteristics of large specific surface area, high surface activity, large adsorption capacity for organic pollutants, and strong adsorption affinity. Therefore, it can be used as a high-efficiency adsorbent for potential organic pollutants. Such as the literature [Sun Mingli, Cheng Rongming, Xu Xuecheng. et al. Research on the adsorption of phenol and substituted p...
