When the mixtures of La(III) and Ba(II) were extracted for 5 min at pH 4.5, only lanthanum(III) was extracted quantitatively, whereas barium(II) remained in the aqueous phase. After the phases were separated, barium(II) was extracted quantitatively for 5 min at pH 7.9 again. Then, the two phases were each shaken with 0.1 M HCl in order to back-extract lanthanum(III) and barium(II) from the organic phases; both metal ions were determined by ICP-AES. In the process, lanthanum(III) and barium(II) TTA chelates in o-dichlorobenzene formed stable adducts with DB18C6 (La(TTA)_3・nDB18C6 and Ba(TTA)_2・nDB18C6, n = 0 - 2). The stability constants(β_n) of the adducts determined by means of curve-fitting method were log β_1 = 3.7 and log β_2 = 5.9 for lanthanum(III), and log β_1 = 3.8 and log β_2 = 7.9 for barium(II). The extraction constant(log K) of lanthanum (III) adduct was - 3.7.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Analytical Chemistry = 日本分析化学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.49.895","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.or.jp/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002905799/en/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/article/bunsekikagaku/49/11/49_895/_article/-char/ja","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2000 The Japan Society for Analytical Chemistry"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"土田, 友一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本浄, 高治"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-HONJO-T-895.pdf","filesize":[{"value":"213.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-HONJO-T-895.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10347/files/SC-PR-HONJO-T-895.pdf"},"version_id":"c34be7c7-3c28-4280-8dfb-0c26ea18b1c5"}]},"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":"テノイルトリフルオロアセトンとクラウンエーテルによるランタン(III)とバリウム(II)の協同抽出分離","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テノイルトリフルオロアセトンとクラウンエーテルによるランタン(III)とバリウム(II)の協同抽出分離"},{"subitem_title":"Separation of lanthanum (III) and barium (II) as their thenoyltrifiuoroacetone complexes with dibenzo-18-crown-6 by means of synergistic extraction","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10347","relation_version_is_last":true,"title":["テノイルトリフルオロアセトンとクラウンエーテルによるランタン(III)とバリウム(II)の協同抽出分離"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:41:59.978992+00:00"}
