Abstract
A method is provided for removing organic impurities in the recycling of phosphors from fluorescent lamps. Particles created from the lamps are washed with a bleaching agent to decompose the organic materials. The organic materials are thereby solubilized and can be removed. The phosphors can then be recovered and reused to manufacture fluorescent lamps.
