摘　　要：采用纳米TiO2改性羊毛纤维滤料来净化室内空气中的SO2.在实验中选用两浸两渍的方法制备纳米TiO2改性羊毛纤维,对整理后的羊毛纤维进行静态实验测试,并绘制吸附效果曲线图.实验测得“滤料1原样”对静态实验箱内SO2的净化率为9％,“滤料1整理样”对SO2的净化率为10％,紫外光灯照射后,“滤料1～5整理样”对SO2的过滤效率分别为53％、59％、60％、65％、71％.实验结果表明：无紫外光灯照射时,滤料整理前后对SO2的净化率相差不大.在紫外光灯照射下,滤料整理样对SO2的净化率呈几何型提高.This paper used the wool fiber modified by nano-TiO2 to filter the indoor sulfur dioxide. The experiment used the method of two leaching and two stains to prepare the wool fiber modified by nano-TiO2, then did the static state experimental test on those Wool Fiber. The experiment datas were analysised by drawing the effect of adsorption curve. The degradation rate of sulfur dioxide of ＂The original sample 1＂ in the static state experiment box was 9% by experimental measurement, while it is 10% for the ＂the modified sample 1＂. With the UV light, the filtration efficiency of sulfur dioxide were 53%, 59%, 60%, 65%, 71% for ＂The modified sample 1-5＂, correspondingly. The results showed that： Without the UV light, the degradation rates of sulfur dioxide of two samples are almost the same, however, with the UV light, this rate increased geometrically for the modified samples.
