Abstract
As a part of fundamental studies on the collection of lithium from sea water, ion exchange experiments were performed by using a resin of the ion retardation type.
By using Retardion 11A-8 as adsorbent and pure water as elutant, lithium in natural sea water (Li Concentration 0.09 mg/l) was concentrated by factor larger than two, as the result of which Lithium concentration of initial part of elutes reached more than 0.2 mg/i. The multistage ion exchange was much effective to the enrichment of lithium in sea water.
