The extraction of lanthanides with HPBI was investigated in the presence and absence of tri-n-octylphosphine oxide. HPBI was found to be a very powerful extractant for lanthanides owing to its strong acidity. The acidity and extractability are discussed on the basis of the molecular structure optimized by a semi-empirical MNDO/H calculation."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137044804535552","@type":"Researcher","foaf:name":[{"@value":"Quyen Thi Hanh Le"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137044804535554","@type":"Researcher","foaf:name":[{"@value":"Shigeo Umetani"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137044804535555","@type":"Researcher","foaf:name":[{"@value":"Hideki Takahara"}]},{"@id":"https://cir.nii.ac.jp/crid/1381137044804535553","@type":"Researcher","foaf:name":[{"@value":"Masakazu Matsui"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00032670"}],"prism:publicationName":[{"@value":"Analytica Chimica Acta"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"1993-02","prism:volume":"272","prism:number":"2","prism:startingPage":"293","prism:endingPage":"299"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:0003267093805826?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:0003267093805826?httpAccept=text/plain"}],"createdAt":"2002-07-25","modifiedAt":"2019-05-06","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360002219104191744","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Highly Acidic Extractant, 4-Benzoyl-3-phenyl-5-isoxazolone: The Synergistic Extraction of Alkaline Earth and Alkali Metals Combined with Trioctylphosphine Oxide or Bis(diphenylphosphinyl)methane"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846644034283520","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Steric Control of Selectivity for Lanthanoids in Liquid–Liquid Extraction with Tris- and Tetrakis(pyrazol-1-yl)borate–<i>β</i>-Diketon Mixed-Ligand Systems"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679229310464","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Solvent Extraction of Lanthanoids(III) with Dinitrobenzoyl-N-phenylhydroxylamine."}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/0003-2670(93)80582-6"},{"@type":"OPENAIRE","@value":"doi_dedup___::c1d125efac73593769c8f1d2672a55da"},{"@type":"CROSSREF","@value":"10.1246/bcsj.68.172_references_DOI_2H4q6Ss1AfEXgTa7Ccg9NV2dqaC"},{"@type":"CROSSREF","@value":"10.2116/analsci.10.315_references_DOI_2H4q6Ss1AfEXgTa7Ccg9NV2dqaC"},{"@type":"CROSSREF","@value":"10.1246/bcsj.68.2867_references_DOI_2H4q6Ss1AfEXgTa7Ccg9NV2dqaC"}]}
