By adding macrocyclic ligand to the aqueous phase　in the conventional chelate extraction system, the extractions of metal ions with　larger ionic radii shifted to the higher pH region. Consequently, the separation among the metal ions was enhanced. Diazapolyoxabicyclic ligands（cryptand） exhibit a prominent separation ability for alkali and alkaline earths metal ions. Quantitative separation systems have been successfully developed in the synergistic extraction of alkali and alkaline earth metal ions in the presence of　cryptand. A new type of water-soluble sulfonated crownethers have been prepared. The extractive separability of lanthanide ions was found to improve by　adding the sulfonated crown ethers into the aqueous phase. The number of water　molecules in the first coordination sphere of the central Eu^3＋ in the complex was determined by a laser-induced luminescence study. In addition, fluorescence spectra were measured to evaluate the structure of the complexes. The stabilization of the complexes formed is discussed taking into account an outer-sphere electrostatic attraction between the sulfonic acid group and the metal ion.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本素材物性学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10140273","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09199853","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"梅谷, 重夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umetani, Shigeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"sozai17-1a.pdf","filesize":[{"value":"706.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai17-1a.pdf","url":"https://air.repo.nii.ac.jp/record/822/files/sozai17-1a.pdf"},"version_id":"3228a2ae-11e0-4858-b176-1edacfed2165"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"大環状配位子","subitem_subject_scheme":"Other"},{"subitem_subject":"マスキング試薬","subitem_subject_scheme":"Other"},{"subitem_subject":"金属イオン","subitem_subject_scheme":"Other"},{"subitem_subject":"vent　Extraction","subitem_subject_scheme":"Other"},{"subitem_subject":"High Selectivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Masking effect","subitem_subject_scheme":"Other"},{"subitem_subject":"Mceocyclic Ligand","subitem_subject_scheme":"Other"},{"subitem_subject":"Alkaline Earth Metal","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"　大環状配位子をイオンサイズ選択性マスキング試薬として利用した金属イオンの高選択的溶媒抽出系の設計","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"　大環状配位子をイオンサイズ選択性マスキング試薬として利用した金属イオンの高選択的溶媒抽出系の設計"}]},"item_type_id":"10001","owner":"3","path":["666"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-05"},"publish_date":"2008-03-05","publish_status":"0","recid":"822","relation_version_is_last":true,"title":["　大環状配位子をイオンサイズ選択性マスキング試薬として利用した金属イオンの高選択的溶媒抽出系の設計"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T12:00:59.894059+00:00"}
