Abstract

A method for regenerating a fluorescentmaterial, which comprises a step of recovering at least one selected from a fluid containing a fluorescent material having been used for forming a fluorescent film of a fluorescent lamp and a solidified material containing the fluorescent material, a step of adding water to the recovered fluid containing fluorescent material and/or the solidified material containing fluorescent material, to prepare a fluorescent material-containing fluid, a step of adding an acid to the fluorescent material-containing fluid, to adjust the pH thereof to 4 to 6, and a step of adding an oxidizing agent to the fluorescent material fluid having an adjusted pH; and a fluorescent lamp which uses a fluorescent material or regenerated by the use of the above method for regenerating a fluorescent material.
