摘要
为测定一种新型长效光催化消毒剂在旅客列车应用的抗菌性能,在某铁路普速和高铁旅客列车上分别用新型长效光催化消毒剂喷涂车厢内表面,通过无菌棉签拭子涂抹试验组和对照组列车不同位点同等面积的表面,经实验室培养后涂平皿,进行菌落计数。在普速和高铁列车的小桌板、座椅靠背、卫生间内壁、卫生间外壁和行李架下沿,试验组的菌落计数均显著低于对照组(n=9,P<0.05);普速和高铁列车试验组各位点的菌落计数明显低于公共场所公共用品用具卫生限值(≤300 CFU/25 m^(2))。说明新型长效光催化消毒剂能显著降低旅客列车物体表面的菌落计数,具有长效优异的抗菌性能。
The antibacterial performance of a novel long-acting photocatalytic disinfectant applied in passenger trains was evaluated.A noval long-acting photocatalytic disinfectant was sprayed on the inner surface of the train carriages of a certain railway ordinary and high-speed passenger trains.Sterile cotton swab was applied to the same area of the train surface at different points in the experimental and control groups,which was further cultured in the laboratory and smeared on the plate for colony counting.The results showed that the colony count of the experimental group was significantly lower than that of the control group(n=9,P<0.05)on the tray table,seat backrests,inner and outer walls of the toilet,and under the luggage rack of the ordinary and high-speed railway trains.The bacterial count at various points of the experimental group of the ordinary and high-speed trains is significantly lower than the hygiene limit for public goods and tools in public places.(≤300 CFU/25 m^(2)).These show that the new long-lasting photocatalytic disinfectant can significantly reduce the bacterial count on the surface of passenger train objects,and has long-lasting and excellent antibacterial properties.
