| 摘 要： | 目的研究以纳米二氧化钛为主体原料制成的空气净化喷雾剂降解甲醛的效果。方法选取20对房间随机分成2组，一组用纳米二氧化钛空气净化喷雾剂治理，另一组作对照，24h后同时测定2组房间内的甲醛浓度。结果治理24h后治理组房间甲醛含量显著低于对照组（t=7．417，v=9，P=0．000）。结论纳米二氧化钛空气净化喷雾剂对甲醛有显著的降解效果。 |

| Abstract: | [ Objective ] To research the degradation of formaldehyde by air spray decontaminant, which using nanometer TiO2 as main precursor. [ Methods] 20 pairs of rooms randomly divided into two groups, one group was treated by nanometer TiO2 spray decontaminant, another as the control group. 24 hours later, the concentrations of formaldehyde in indoor air of two groups were determined at the same time. [ Results ] The concentration of formaldehyde in the treated group was significantly lower than that in the control group （ t =7. 417, v = 9, P = 0. 000）. [Conelusion] The nanometer TiO2 spray decontaminant is effective in degradation of formaldehyde. |
