The influence of pH and temperature on the efficiency of chlorine inactivation of two unrelated picornaviruses in a typical urban wastewater effluent was examined. Temperature, unlike pH, had relatively little effect on the rate of inactivation. The pH effect was complex and the two viruses differed. The f2 coliphage was more sensitive to chlorine at low pH, but at all values there was a threshold above which additional chlorine resulted in very rapid inactivation. The amount of chlorine required for this was less at low than at high pH, although at pH values above 7 the extent of inactivation was about the same. There was no apparent correlation between pH and rate of inactivation of poliovirus but there was a suggestion that at a pH close to the isoelectric point of the virus it was less sensitive to chlorination.
研究了pH值和温度对典型城市污水中两种不相关小RNA病毒氯灭活效率的影响。与pH值不同，温度对灭活速率的影响相对较小。pH值的影响较为复杂，两种病毒有所不同。f2噬菌体在低pH值下对氯更敏感，但在所有pH值下都存在一个阈值，高于该阈值额外的氯会导致非常快速的灭活。低pH值时达到此效果所需的氯量比高pH值时少，尽管在pH值高于7时灭活程度大致相同。pH值与脊髓灰质炎病毒的灭活速率之间没有明显的相关性，但有迹象表明，在接近病毒等电点的pH值下，它对氯化作用不太敏感。
