Abstract

PURPOSE: To make glass pieces a discarding-possible condition, by separating Hg from the waste of a fluorescent lamp by forming water-unsoluble HgS, etc. by contacting metallic Hg contained in the fluorescent lamp, which life expires, and mercury oxide mixed in the Hg with H2S.
CONSTITUTION: After breaking a fluorescent lamp, which life expires, H2S is introduced during the time when the broken lamp is mixed and agitated with spongy rubber pieces, and mercury oxide mixed in metallic Hg is changed into HgS, etc. by the following reaction. HgO+H2S→HgS+H2O Hg2O+H2S→HgS+Hg+H2O Water-unsoluble HgS and Hg are removed from glass pieces
