| 摘 要： | 为了分析流速、湿度、温度对室内污染物甲醛的光催化氧化影响,在搭建光催化氧化分析动态实验台的基础上,利用浸渍准膜法制得TiO2光催化剂薄膜,并进行甲醛的光催化去除实验。结果表明,随着流速的增加,污染物的光催化氧化逐步由传质控制过程过渡到光催化氧化控制过程,湿度对甲醛的光催化氧化存在一最佳范围,温度对甲醛的光催化氧化无明显影响。

| Abstract: | The dynamic experimental system was constructed in order to study the effects of the flow rate,humidity and temperature on the photocatalytic decomposition of formaldehyde.Titanium dioxide(TiO_2) film was prepared by dipping method.The results shown that the photocatalytic degradation of formaldehyde controlled by mass transfer transited to photocatalytic control with the increasing of flow rate.There existed an optional humidity to the photocatalytic decomposition of formaldehyde,but the temperature's effect on the photocatalytic decomposition of formaldehyde was not obvious. |
