FIELD: chemistry.
SUBSTANCE: acid solution is added to solid waste from production of AB-17-8 anionite and zinc salt solution is obtained, which is which solid impurities are removed. Alkali solution is added to the purified solution, obtaining a zinc hydroxide precipitate, which is separated from the liquid phase and washed with water. Aqueous suspension of the obtained zinc hydroxide is treated with a solution of chromium anhydride with precipitation of zinc silicate glass.
EFFECT: invention provides for recycling wastes from production of AB-17-8 anionite and preventing its adverse effect on the environment, reducing financial expenses on producing zinc silicate glass.
