Effect of structure on the sorption properties of chlorine-containing form of double aluminum lithium hydroxide

Abstract

The effect exerted by composition and specific structural properties of commercial batches of granular sorbent based on chlorine-containing form of double aluminum lithium hydroxide on its sorption properties in lithium extraction from magnesium chloride brines was determined. Deficiency in lithium chloride in the sorbent structure and structural defects are responsible for the selectivity of granular sorbent. It was shown that sorbent is selective for lithium even in the presence of high concentrations of magnesium chloride in brine and the borate ions exhibit adverse effect on the technological process.
