为探讨二氧化氯（ＣｌＯ２） 的消毒效果，应用酶联免疫吸附实验（ ＥＬＩＳＡ） ，研究了ＣｌＯ２ 对乙型肝炎病毒表面抗原（ ＨＢｓＡｇ） 的灭活效果并与液氯（Ｃｌ２） 进行对比。结果表明：２－５ ｍ ｇ／Ｌ 的ＣｌＯ２ 可使５８－４ ％ 的ＨＢｓＡｇ 灭活，１２－５ ｍｇ／Ｌ 的Ｃｌ２ 可灭活５２－２ ％ 的ＨＢｓＡｇ ；在不同的ｐ Ｈ 条件下，ＣｌＯ２ 对ＨＢｓＡｇ 的灭活效果都高于Ｃｌ２ ，在ｐＨ ＝ ７ 消毒效果最好；２５ｍｇ／Ｌ ＣｌＯ２ 作用２０ ｍｉｎ 可使９７－２ ％ 一定浓度的ＨＢｓＡｇ 灭活。而２５ ｍ ｇ／Ｌ Ｃｌ２ 经过６０ ｍｉｎ 只能使７０－２ ％ 相同浓度的ＨＢｓＡｇ 灭活，说明ＣｌＯ２ 是一种高效、快速饮用水消毒剂
To investigate the disinfection effect of chlorine dioxide (ClO2), the effect of ClO2 on the inactivation of hepatitis B virus surface antigen (HBsAg) was studied by enzyme linked immunosorbent assay (ELISA) and compared with that of liquid chlorine (Cl2). The results showed that 58-4% HBsAg could be inactivated by ClO2 at 2-5 m g / L, 52-2% HBsAg at 12-5 mg / L Cl2, ClO2 Inactivation of HBsAg was higher than that of Cl2, and disinfection was the best at pH = 7. When treated with 25 mg / L ClO2 for 20 min, 97-2% HBsAg was inactivated. However, after 60 min of 25 m g / L Cl2, only 70-2% of HBsAg in the same concentration could be inactivated, indicating that ClO2 is an efficient and rapid drinking water disinfectant
