摘　　要：利用环境测试舱模拟不同光源种类和光照强度下的室内环境,以甲醛溶液的光催化降解为探针反应,分析Ce-TiO2光催化降解甲醛溶液效果与光源的关系。并且采用指数平滑法中的3次指数平滑模型,建立Ce-TiO2光催化降解甲醛溶液效果的预测模型,预测结果表明实测值与预测值误差小,预测值精确度高,这为光催化降解甲醛溶液的研究,提供了一个新的思路。Simulating different types of light sources and light intensities of the indoor environment by using environmental test chamber, and taking the photocatalytic activity for degradation of formaldehyde solution as the probe reaction, we analyzed the relationship between light sources and the effects of photocatalytic activity of Ce- TiO2 for degradation of formaldehyde solution. By using the cubic exponential smoothing method, the prodiction model for the effects of photocatalytic activity of Ce-TiO2 for degradation of formaldehyde solution was estab- lished, the prodiction results showed that the error between the measured values and predicted values was small and the prediction accuracy was high, which provided a new way for the study of photocatalytic activity for degra- dation of formaldehyde solution.
