The pH value of the solution was maintained at ca. 10 by adding Na2CO3 in the solution. No catalytic action of Cu2+ ion was observed. The rate of oxidation was not virtually affected by the temperature, but increased with the rise of the flow rate of air. A zero order rate equation was found. From the presumption that the reaction is composed of the sequential steps of dissolution of gaseous oxygen at the surface of rising air bubbles and the oxidation of Fe2+ ion and Fe(OH)2 precipitate by the dissolved oxygen, it was revealed that the rate determining step of the overall reaction is the step of oxygen dissolution. From the rate constant of the rate equation, the liquid-film mass transfer coefficient of dissolved oxygen in the liquid boundary layer at the bubble surface was estimated, and it was fairly well coincident with the directly measured values. The rise of the rate of oxidation with the flow rate of air stream was interpreted in terms of the increase in the surface area of rising air bubbles.","subitem_description_type":"Abstract"}]},"item_10002_publisher_9":{"attribute_name":"出版者（別表記）","attribute_value_mlt":[{"subitem_publisher":"National Institute of Technology, Tsuyama College"}]},"item_10002_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-7066","subitem_source_identifier_type":"ISSN"}]},"item_10002_source_id_12":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00149351","subitem_source_identifier_type":"NCID"}]},"item_10002_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"430","subitem_subject_scheme":"NDC"}]},"item_10002_text_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_text_value":"津山工業高等専門学校"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tsuda, Akihiro"}],"nameIdentifiers":[{"nameIdentifier":"8199","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higuchi, Binzo"}],"nameIdentifiers":[{"nameIdentifier":"8200","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"8201","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":"1978-10-20"}],"displaytype":"detail","filename":"津山工業高等専門学校紀要_16-2.pdf","filesize":[{"value":"442.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"津山工業高等専門学校紀要_16-2.pdf","url":"https://tsuyama-nit.repo.nii.ac.jp/record/1505/files/津山工業高等専門学校紀要_16-2.pdf"},"version_id":"3f959d9e-5e84-4996-a503-72908a44cbb4"}]},"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":"Air Oxidation of Aqueous Ferrous Sulfate Solution in the Alkaline Region","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Air Oxidation of Aqueous Ferrous Sulfate Solution in the Alkaline Region"}]},"item_type_id":"10002","owner":"4","path":["22"],"pubdate":{"attribute_name":"公開日","attribute_value":"1978-10-20"},"publish_date":"1978-10-20","publish_status":"0","recid":"1505","relation_version_is_last":true,"title":["Air Oxidation of Aqueous Ferrous Sulfate Solution in the Alkaline Region"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-07-25T10:18:06.201706+00:00"}
