摘要
主要研究负载纳米TiO2对室内甲醛的降解情况。采用溶胶-凝胶法和粉体负载法来制备纳米TiO2,利用吸附床装置在紫外灯、日光灯照射下测定不同制备条件下的负载纳米TiO2的穿透时间(最长可达8 h)和吸附容量(最高可达0.719 3 mg/g),结果表明粉体负载法制备的负载纳米TiO2吸附甲醛效果比溶胶-凝胶法制备的吸附效果好。因此确定了750℃负载纳米TiO2为最佳吸附剂。
This article mainly researched load nano - titanium dioxide that degraded the indoor formaldehyde. Adopting sol - gel and powder load method to prepare nano - titanium dioxide, using adsorber device and UV lamps, fluorescent radiation measured penetration load time（ up to a maximum of 8 hours）and adsorption capacity （up to a maximum of 0.719 3 mg/g） under the conditions of different preparation of nano - titanium. The results showed that the efficiency of powder load method prepared by the load nano - titanium dioxide was better than sol - gel method. Therefore identified 750℃ load nano - titanium dioxide as the best adsorbent.
