Detoxification effect of chlorination procedure on waste lead glass

This work reports the detoxification effect of chlorinating volatilization procedure on waste lead glass. The effects of various reaction parameters on lead removal efficiencies were examined, and the optimal operation conditions were 1000 °C, 2 h, and 600 ± 50 Pa, respectively. Moreover, it was found that the residues could be safely applied in a wide range, e.g., for wollastonite synthesis by an environmental benign technique. Accordingly, the typical hazardous waste was successfully converted into a safe raw material for further industrial application.
