Claims (2)

1. Способ обезвреживания ртутьсодержащего люминофора в виде продукта переработки вышедших из строя люминесцентных ламп, включающий обработку люминофора раствором демеркуризатора, отличающийся тем, что для перевода люминофора в группу безопасных отходов минерального происхождения, его обработку осуществляют в два этапа, на первом из которых люминофор переводят в сульфид ртути за счет смешивания с раствором демеркуризатора до получения тестообразной смеси, при этом в качестве демеркуризатора используют 10%-ный водный раствор полисульфида кальция в количестве, составляющем не менее 400 мл раствора на 1000 г сухого люминофора, а на втором этапе полученный сульфид ртути переводят в инертное поликристаллическое состояние путем ввода в него стабилизатора в виде порошка окиси кальция из расчета не менее 50 г окиси кальция на 1000 г люминофора, который после смешивания выдерживают до отверждения смеси.1. A method of neutralizing a mercury-containing phosphor as a product of the processing of failed fluorescent lamps, comprising treating the phosphor with a solution of a demercurizer, characterized in that for transferring the phosphor into a group of safe waste of mineral origin, it is processed in two stages, in the first of which the phosphor is converted into mercury sulfide due to mixing with a solution of a demercurizator to obtain a pasty mixture, while a 10% aqueous polysulf solution is used as a demercurizator yes calcium in an amount of at least 400 ml of solution per 1000 g of dry phosphor, and in the second stage, the resulting mercury sulfide is converted into an inert polycrystalline state by introducing a stabilizer in the form of calcium oxide powder based on at least 50 g of calcium oxide per 1000 g phosphor, which after mixing is kept until the mixture is cured. 2. Способ по п.1, отличающийся тем, что отверждение смеси осуществляют не менее чем через 20 мин после смешения люминофора с раствором демеркуризатора.2. The method according to claim 1, characterized in that the curing of the mixture is carried out at least 20 minutes after mixing the phosphor with a solution of demercurizator.
