A Novel Process for Cathode Ray Tube Glass Detoxification
A novel process for the treatment of hazardous waste -- Cathode Ray Tube (CRT) glass, based on self-propagating reaction, was proposed. In the process, various types of CRT glass powders were blended with suitable amount of ferric oxide and magnesium, and the mixtures could generate self-propagating reaction once ignited by a thermal source. Generally, the self-propagating reaction could be well maintained when the CRT glass content in the mixture was no more than 60 wt.%, and the combustion wave velocity decreased along with the increase of glass amount. XPS experiments showed that heavy elements in the final products became more stable and was solidified during the process. Leaching tests demonstrated that heavy metals in the final products fulfilled the environmental regulations of USEPA.
