Acetic and nitric acids were extracted from the waste acid mixture, and phosphoric acid, which was the main components, was left in the raffinate. Tri-octyl phosphate (TOP) was used as an extractant to extract acetic and nitric acids. Fundamental studies were carried out for extraction and stripping of acetic, nitric and phosphoric acids, and a demonstration test was conducted using a mixer-settler equipment.TOP selectively extracts acetic and nitric acids from the waste acid mixture mainly containing phosphoric acid. Extraction of acetic and nitric acids is approximately 100% by applying the continuous countercurrent extraction with a phase ratio (A/O) of 0.4 and 6-stage extraction using TOP as an extractant. Acetic and nitric acids extracted in TOP are stripped with water as a stripping agent at 99 % and 99.5% under the conditions of a phase ratio (O/A) of 1.0 and 4-stage stripping. In the demonstration test using a mixer-settler equipment, 95% of acetic acid and 98% of nitric acid in the waste acid mixture were extracted, and phosphoric acid was left in the raffinate to give crude phosphoric acid as a product.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"化学工学会","subitem_publisher_language":"ja"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00037234","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0386216X","subitem_source_identifier_type":"PISSN"}]},"item_9_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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"芝田, 隼次","creatorNameLang":"ja"},{"creatorName":"Shibata, Junji","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"森川, 正貴","creatorNameLang":"ja"},{"creatorName":"Morikawa, Masataka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"芳川, 典生","creatorNameLang":"ja"},{"creatorName":"Yoshikawa, Norio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 智子","creatorNameLang":"ja"},{"creatorName":"Yamada, Tomoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村山, 憲弘","creatorNameLang":"ja"},{"creatorName":"Murayama, Norihiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"山本, 秀樹","creatorNameLang":"ja"},{"creatorName":"Yamamoto, Hideki","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":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20030720-10.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20030720-10.pdf","objectType":"fulltext","url":"https://kansai-u.repo.nii.ac.jp/record/11300/files/KU-1100-20030720-10.pdf"},"version_id":"b12dc5b6-1965-48c2-9b59-eeffe876425c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"solvent extraction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"liquid crystal display","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"waste acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phosphoric acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"etching solution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"zero emission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"関西大学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","subitem_subject_language":"en","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":"液晶製造工程から排出されるリン酸を主成分とする廃酸からの酸の分離回収","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液晶製造工程から排出されるリン酸を主成分とする廃酸からの酸の分離回収","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1594"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-11-09"},"publish_date":"2011-11-09","publish_status":"0","recid":"11300","relation_version_is_last":true,"title":["液晶製造工程から排出されるリン酸を主成分とする廃酸からの酸の分離回収"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-10-26T06:39:19.346448+00:00"}
