目前,我国乙型肝炎发病率呈持续上升趋势。在饮水、食品、公共场所以及医院实施广泛和严格的消毒,是切断传播途径,抑制发病率上升的有效手段。为了解氯化异氰尿酸类消毒剂对乙型肝炎表面抗原的破坏作用,我们合成了三氯异氰尿酸并采用酶联免疫吸附试验（ELISA）法加以检测。现将结 At present, the incidence of hepatitis B in our country is on the rise. Extensive and rigorous disinfection in drinking water, food, public places and hospitals is an effective means of cutting off the route of transmission and inhibiting the rising incidence. To understand the destructive effect of chlorinated isocyanuric acid disinfectants on hepatitis B surface antigen, we synthesized trichloroisocyanuric acid and detected it by ELISA. Now will end
