Lithium　ion　transfered　into　organic　phase　from　exchanged　mother　liquids　of　Li-LSX　zeolite　after　extraction　by　tri-n-butyl　phosphate　(TPB).　In　this　article,　the　anti-extraction　of　lithium　ion　from　TBP　by　hydrochloric　acid　was　studied.　And　the　effects　of　phase　ratio,　hydrochloric　acid　concentration　and　temperature　on　the　anti-extraction　technology　were　analyzed　in　details.　The　optimal　anti-extraction　conditions　are　found　as　following:　phase　ratio　is　about　1:1;　hydrochloric　acid　concentration　is　more　than　5　mol/L;　room　temperature.　Furthermore,　the　recycling　of　extractant　and　the　industrial　prospect　of　this　method　were　investigated　preliminarily.
