ABSTRACT:
A fluorescent lamp phosphor product is recovered from a degraded aqueous suspension by treating a separated solids portion of the suspension with nitric acid to solubilize a decomposed portion of a rare earth activated yttrium oxide phosphor and form a remaining mixture of phosphors which may be reconstituted to a fluorescent lamp phosphor product suitable for use in a lamp.
