ABSTRACT:
Both ends of a bulb of a waste fluorescent lamp are cut off, a phosphor layer formed on an interior surface of the bulb is detached, so that mercury-containing phosphor powder can be obtained. The mercury-containing phosphor powder is subjected to a heating and reducing process with the dry-method, by mixing an organic reducing agent with the phosphor powder and heating the mixture, to vaporize and separate mercury from the phosphor powder. The vaporized mercury is then cooled and condensed, to collect mercury.
