The behavior of Pa(IV) in the perchloric acid solution was investigated by the TTA-benzene extraction method. It was found that the PaOH^<3+> ion existed predominantly in a 0.03-3 M perchloric acid solution at the ionic strength of 3. The reaction of TTA extraction may proceed as : PaOH^<3+>+4HA = PaA_4+H_2O+3H^+ or PaOH^<3+>+4HA = Pa(OH)A_3(HA)+3H^+ The distribution ratio of Pa(IV) in the system using Eu(II) as the reductant is about ten times as large as that in the system using Cr(II) as the reductant. It was considered that a non-extractable complex may be formed between Pa(IV) and Cr(III), while such a complex may not be formed when Eu(II) is used as the reductant.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"60702 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408808","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00836167","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"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":"KAWASUJI, Isamu"}],"nameIdentifiers":[{"nameIdentifier":"108549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SATO, Akiko"}],"nameIdentifiers":[{"nameIdentifier":"108550","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SUZUKI, Shin"}],"nameIdentifiers":[{"nameIdentifier":"108551","nameIdentifierScheme":"WEKO"}]}]},"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":"KJ00004198322.pdf","filesize":[{"value":"60.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004198322.pdf","url":"https://tohoku.repo.nii.ac.jp/record/46367/files/KJ00004198322.pdf"},"version_id":"61144e80-b7a9-4c11-b1d2-eeaf562f1ec8"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The Chemistry of Protactinium : XI.
