摘    要:利用光触媒钛羟基磷灰石网膜(PTAF)具有吸附和酶催化的特点,研究其对SARS病毒的抑制作用.实验结果表明在紫外照射条件下,PTAF膜对SARS冠状病毒的抑制率为100%.在没有紫外照射的条件下,PTAF膜对SARS冠状病毒的抑制率为99.99%, 与对照组相比,PTAF膜抑制病毒的效率是HAF膜的1 000倍以上.研究结果提示,PTAF在预防SARS冠状病毒及其他病毒性疾病流行方面有潜在的应用价值.

关 键 词:光触媒钛羟基磷灰石网膜,SARS冠状病毒,光催化作用

Abstract:Photocatalytic titanium apatite filter (PTAF) is a new material that has been reported to have an ability to absorb and inactivate bacteria. The inactivation effect of PTAF on serious acute respiratory syndrome coronary virus (SARS-CoV) was tested. The results showed that PTAF filter inactivated/decomposed SARS CoV up to 99.99% after 6 h interaction under the condition of non-UV irradiation. However, under the condition of UV irradiation, PTAF and HAF both were able to inactivate/decompose SARS CoV completely. The study has provided the first evidences that PTAF could inactivate SARS-CoV virus, suggesting that the PTAF material will be applied for the prevention of SARS-CoV as well as other viruses.
Keywords:photocatalytic titanium apatite filter (PTAF)  serious acute respiratory syndrome coronary virus (SARS CoV)  photocatalysis
