Q2・ZnL2の順に増加し1-ノナノールへのイオン対の親和性がこの順に大きくなることを示唆する結果を得た.また,イオン対分配定数の差はいずれのイオン対,(Q+)2・ML22-に対しても1-ノナノール濃度が増加するとともに大きくなることが観察された.これに対して,1-ノナノール濃度が減少するに連れてその差は小さくなり,オクタン純溶媒系では非常に小さくなることが予想される結果を得た.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_10001_relation_34":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.2116/bunsekikagaku.52.731"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.2116/bunsekikagaku.52.731","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID(NCID)","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"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":"内田, 賢宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"安井, 孝志"},{"creatorName":"ヤスイ, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"Yasui, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"内藤, 哲義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 硯道"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-20"}],"displaytype":"detail","filename":"JA 52_731.pdf","filesize":[{"value":"387.6 kB"}],"format":"application/pdf","license_note":"c 2003 The Japan Society for Analytical Chemistry","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/3552/files/JA 52_731.pdf"},"version_id":"bca32448-81ce-4d8d-bf66-6df3c1ab79d8"}]},"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":"1-ノナノール/オクタン混合溶媒を用いる2-(2-ピリジルアゾ)-1-ナフトール-4-スルホン酸イオンとその2価金属陰イオン錯体のテトラブチルアンモニウムイオンによる抽出機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1-ノナノール/オクタン混合溶媒を用いる2-(2-ピリジルアゾ)-1-ナフトール-4-スルホン酸イオンとその2価金属陰イオン錯体のテトラブチルアンモニウムイオンによる抽出機構"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-07-01"},"publish_date":"2013-07-01","publish_status":"0","recid":"3552","relation_version_is_last":true,"title":["1-ノナノール/オクタン混合溶媒を用いる2-(2-ピリジルアゾ)-1-ナフトール-4-スルホン酸イオンとその2価金属陰イオン錯体のテトラブチルアンモニウムイオンによる抽出機構"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-16T14:30:20.305064+00:00"}
