设计了一种内壁为高反射率材料的简易消毒箱．将纸币表面涂以化学消毒剂放入消毒箱中，用紫外线照射进行协同杀菌作用．试验表明，紫外线与体积分数为０．０１的新洁尔灭协同作用５ｓ，纸币表面菌的杀灭率可达９９．９９％．
A simple disinfection chamber with high reflectivity material was designed. The surface of banknotes coated with chemical disinfectant into the disinfection box, with UV irradiation synergistic bactericidal effect. Experiments show that UV and volume fraction of 0.01 benzalkonium synergistic effect of 5s, the killing rate of paper surface bacteria up to 99.99%.
