摘要
纳米二氧化钛晶体胶体膜的光催化降解研究实验表明,在普通的日光灯下,经过72h的照射,苯与甲苯的降解率分别为96.7%和97.7%,乙硫醇、甲醛与氨几乎100%降解。实际居室环境实验应用研究结果显示,经过纳米二氧化钛胶体处理后的居室,一周后其空气质量达到相应国家标准。因此,纳米二氧化钛胶体形成的纳米晶体膜对空气污染净化是非常有效的,并具有良好的杀菌防霉效果。
Experimental results of photocatalyzed degradation of nano-TiO2 crystalline colloidal films showed that benzene and toluene were removed 96.7% and 97.7% separately with daylight lamp after 72h, and that ethanethiol, formaldehyde and ammonia were removed nearly 100%. After treatment with nano-TiO2 crystalline colloids, the quality of indoor air can satisfy national standard. Nano-TiO2 crystalline films are effectively in cleaning the polluted air, and the films show excellent effect of sterilization and preventing mildew.
