Abstract
The chloride, oxide and metallic species of heavy metal Pb were taken as the research objects in this paper, the effect of incineration temperature, incineration time, HCl gas and moisture on the volatilization of heavy metal Pb was discussed. The results indicate that the volatilization rates of chlorides, oxides and metallic species of heavy metal Pb increase with temperature increasing, the total volatilization rates are in the order of Pb£34PbCl2£34PbO. The effect of time on the volatilization rate of heavy metal Pb is notable before 50 minutes, and the effect of time on Pb is greater than PbCl2 and PbO. The volatilization rates of heavy metal Pb show tendency to rise with increasing HCl, the increasing degree is in the order of PbCl2£34PbO£34Pb. The volatilization rate of PbCl2 increases by an increase in HCl concentration, but if the time is enough (more than 80 minutes), then there is no effect of HCl concentration on PbCl2. The presence of moisture depresses the volatilization rates of chloride, oxide and metallic species of heavy metal Pb, the depressing degree is in the order of PbCl2£34Pb£34PbO.
