The effect of various disinfectants in fumigation on the inactivation of HBsAg

In this study HBsAg was inactived with formalin, formalin plus PP power, peroxyacetic acid and the Chinese medicine (volatile oil). The results showed formalin could inactive HBsAg entirely by natural evaporation for two hours. Peroxyacetic acid (16%) 450 ml for 30 minutes, and 150 ml or 300 ml for 60 minutes could inactive HBsAg also. But the inactivation efficacies of formalin plus PP powder and the Chinese medicine (volatile oil) were poor.
