摘要
用加酸法增强次氯酸钠对乙型肝炎表面抗原的破坏作用。结果表明,含有效氯1500mg/L次氯酸钠溶液加酸调至pH6,作用5分钟可将上述抗原完全破坏。
Destruction of HBsAg is used as an indicator of inactivation of HBV. In order to examine the effect of acidification on destruction of HBsAg by sodium hypochlorite, laboratory and field experiments were carried out. Hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, trichloroacetic acid, tartaric acid and citric acid were used for acidification. When the pH of sodium hypochlorite was adjusted to 6 by above acids, its destructive effect on HBsAg was potentiated significantly. A contact time of longer than 20 min was required to destruct HBsAg by sodium hypochlorite containing 2000 mg/L available chlorine before acidification, while solution containing only 1500 mg/L available chlorine with a 5 min contact time was enough after acidification(pH 6).
