液氯和二氧化氯对病毒灭活作用对比实验研究

Comparative Study on Inactivation Capacity of Chlorine and Chlorine Dioxide on Viruses

应用病毒细胞病变法（ＣＰＥ）研究液氯和二氧化氯对六种病毒［脊髓灰质炎病毒Ⅰ型（ｐｏｌｉｏ＿１）、柯萨奇病毒Ｂ＿３（ＣＶＢ＿３）、艾可病毒１１型，（ＥＣＨＯ＿１１）、腺病毒７型（ＡｄＶ＿７）、单纯性疱疹病毒Ⅰ型（ＨＳＶ＿１）、腮腺炎病毒（ＭＶ）］的灭活作用。结果表明，液氯投置最高浓度达７．０ｍｇ／Ｌ、作用时间６０分钟时对上述六种病毒均达不到灭活效果。而二氧化氯投置仅在１．０ｍｇ／Ｌ、作用时间３０分钟时即可达到灭活效果。二氧化氯在ｐＨ３．０～７．０时对病毒有显著的灭活作用。总之，二氧化氯是一种优于液氯的广谱、高效、快速的饮水杀病毒剂。

The inactivation capacity of Chlorine (Cl_2) and Chlorine Dioxide (ClO_2) on six different kinds of Viruses, including Polio virus 1 (Polio_1) Coxsackie B viruse Ⅲ (CVB_3), ECHO viruse Ⅺ (ECHO_11), adeno virus Ⅶ (Adv_7), herpessimplex viruse 1 (HSV_1), mumps virus (MV), was studied comparatively in vitro. The results showed that Cl_2 in maximal experimental concentration, 7.0mg / L could not kill these six viruses in 60 minutes, while ClO_2 in 1.0mg / L could kill these six viruses completely in 30 minutes. Chlorine dioxide had apparent inativatian capcity under condition of pH 3.0￣7.0. So Chlorine dioxide might be a widerspectum and more efficient anti viral disinfectant for drinking water than chlorine.
