Fundamental studies on the recovery of phosphoric acid were conducted by using Tri-octyl phosphate (TOP) as the extractant for acetic acid and nitric acid. From the results, demonstration tests using a mixer-settler equipment were carried out to obtain crude phosphoric acid. Acetic and nitric acids were selectively extracted by TOP from the waste acid mixture, which contains phosphoric acid as a main component. From the McCabe Thiele analysis, almost all of the acetic and nitric acids were removed by a countercurrent multi-extraction operation of phase ratio(A/O) 0.4 and 6-stage. When TOP loading acids was contacted with the water under the countercurrent operation \nconditions of phase ratio (0/A) 1.0 and 4-stage, 99% of acetic acid and 99.5% of nitric acid were stripped from the organic phase, respectively. From these results obtained by the fundamental studies, a demonstration test was carried out for the extraction of acetic and nitric acids by using a mixer-settler equipment. Consequently, the extractions of acetic and nitric acids in the waste acid mixture were about 95% and 98%, respectively, and crude phosphoric acid can be obtained as a raffinate after the solvent extraction.","subitem_description_type":"Other"}]},"item_10_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"28091","nameIdentifierScheme":"WEKO"}],"names":[{"name":"元田, 善規"}]},{"nameIdentifiers":[{"nameIdentifier":"28092","nameIdentifierScheme":"WEKO"}],"names":[{"name":"森川, 正貴"}]},{"nameIdentifiers":[{"nameIdentifier":"28093","nameIdentifierScheme":"WEKO"}],"names":[{"name":"村山, 憲弘"}]},{"nameIdentifiers":[{"nameIdentifier":"28094","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山本, 秀樹"}]},{"nameIdentifiers":[{"nameIdentifier":"28095","nameIdentifierScheme":"WEKO"}],"names":[{"name":"芝田, 隼次"}]}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学工学部"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00046916","subitem_source_identifier_type":"NCID"}]},"item_10_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04532198","subitem_source_identifier_type":"ISSN"}]},"item_10_version_type_17":{"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":"Motoda, Yoshinori"}],"nameIdentifiers":[{"nameIdentifier":"28086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morikawa, Masataka"}],"nameIdentifiers":[{"nameIdentifier":"28087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama, Norihiro"}],"nameIdentifiers":[{"nameIdentifier":"28088","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90340653","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000090340653"}]},{"creatorNames":[{"creatorName":"Yamamoto, Hideki"}],"nameIdentifiers":[{"nameIdentifier":"28089","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30174808","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000030174808"}]},{"creatorNames":[{"creatorName":"Shibata, Junji"}],"nameIdentifiers":[{"nameIdentifier":"28090","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":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20040000-03.pdf","filesize":[{"value":"11.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20040000-03.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11767/files/KU-1100-20040000-03.pdf"},"version_id":"ec9fcecd-5ecb-4a6e-8eac-1eac674ecf6e"}]},"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":"RECOVERY OF PHOSPHORIC ACID FROM WASTE ACID MIXTURE WITH SOLVENT EXTRACTION","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RECOVERY OF PHOSPHORIC ACID FROM WASTE ACID MIXTURE WITH SOLVENT EXTRACTION"}]},"item_type_id":"10","owner":"1","path":["1624"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-12-15"},"publish_date":"2011-12-15","publish_status":"0","recid":"11767","relation_version_is_last":true,"title":["RECOVERY OF PHOSPHORIC ACID FROM WASTE ACID MIXTURE WITH SOLVENT EXTRACTION"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T14:32:50.864817+00:00"}
