Objective To observe the synergetic virucidal effect by low amperage direct currennt(DC) and free chlorine(FC) for poliovirus Type(PV1) in water.Methods Water samples polluted PV1 was treated by 0.4-1 2mA·cm -2 LDC and 0.2mg·L -1 FC.Inactivation efficacy was estimated by comparing inactivation rates K value and morphologic changes were observed under trasmission electron microscope(TEM).Results There was synergetic effect of inactivating viruses by DC amounting to 1.2 mA·cm -2 or above in combination with 0.2mg·L -1 FC,and synergetic inactivation was significant difference in comparison with FC alone( P 0 05).Under TEM viral gathering grain tended to deconcentration after treated by DC.Conclusion DC might enhance virucidal effect of low level chlorine for poliovirus Ⅰ Type in water.
