Abstract
Изобретение относится к способу очистки воды одновременно от ионов фтора и гуминовых кислот.Способ, согласно изобретению, включает пропускание воды со скоростью потока 0,3 дм3/мин через объем 14…28 см3 сорбента на основе диатомита, модифицированного высокодисперсным гидроксидом алюминия. Модифицированный диатомит получают путем его измельчения и прокаливания, выдерживания в растворе соли алюминия, обработки раствором аммиака, фильтрования, отмывки и сушки на воздухе.
