Abstract

Изобретение относится к способу очистки содержащего примеси бикарбоната лития с помощью катионообменной смолы. Кроме очистки раствора с помощью ионного обмена, стадии обработки включают регенерацию примесных металлов, связанных со смолой. Регенерация состоит из промывки смолы водой, элюирования кислым раствором, промывки водой, нейтрализации щелочным раствором и промывки водой. Способ отличается тем, что нейтрализацию осуществляют раствором гидроксида натрия.
