First, heavy metals in simulated wastewater were adsorbed to the chelating fiber through the nylon mesh with opening of 30 μm. Heavy metals adsorbed to the fiber were successfully desorbed with dilute sulfuric acid at a pH of 1. Next, the leaching of heavy metals from anaerobically digested sewage sludge was conducted by adjusting the pH of the sludge to 2 with sulfuric acid for 48 hours. And then, the pH of the acidified sludge was adjusted to 2.5, 3 and 4 after the addition of nylon mesh bag including the fiber. The optimum pH values in the adsorption with the fiber were 2.5 for Cu, 3 for Pb, and 4 for Cd, Cr, Ni and Zn, respectively. The application of the fibrous chelating agent would be useful for the recovery of soluble heavy metals from acidified sludge without using an acid tolerant solid-liquid separator.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"96203","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIMODA, Wataru"}]},{"nameIdentifiers":[{"nameIdentifier":"96204","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OGAWA, Eriko"}]},{"nameIdentifiers":[{"nameIdentifier":"96205","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ISHIKAWA, Nao"}]},{"nameIdentifiers":[{"nameIdentifier":"96206","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SASAMOTO, Makoto"}]},{"nameIdentifiers":[{"nameIdentifier":"96207","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIBASAKI, Yuji"}]},{"nameIdentifiers":[{"nameIdentifier":"96208","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ITO, Ayumi"}]}]},"item_16_link_13":{"attribute_name":"抄録（URL）","attribute_value_mlt":[{"subitem_link_text":"繊維状キレート剤を用いた酸性化汚泥からの重金属類の吸着除去および回収","subitem_link_url":"https://www.jstage.jst.go.jp/article/jscejer/77/7/77_III_375/_article/-char/ja"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2208/jscejer.77.7_III_375","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021 土木学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21856648","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学大学院 総合科学研究科"},{"subitem_text_value":"いであ株式会社大阪支社河川水工部"},{"subitem_text_value":"岩手大学 理工学部"},{"subitem_text_value":"岩手大学 技術部"},{"subitem_text_value":"岩手大学 理工学部"},{"subitem_text_value":"岩手大学 理工学部"}]},"item_16_version_type_27":{"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":"下田, 渉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小川, 絵莉子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石川, 奈緒"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"笹本, 誠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"芝﨑, 祐二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 歩"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-31"}],"displaytype":"detail","filename":"dgrg-v77n7pIII_375-Ⅲ_383.pdf","filesize":[{"value":"813.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"dgrg-v77n7pIII_375-Ⅲ_383","url":"https://iwate-u.repo.nii.ac.jp/record/15978/files/dgrg-v77n7pIII_375-Ⅲ_383.pdf"},"version_id":"3022230b-114a-4674-b952-1924b406a682"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"anaerobically digested sewage sludge","subitem_subject_scheme":"Other"},{"subitem_subject":"heavy metals","subitem_subject_scheme":"Other"},{"subitem_subject":"chelate resin","subitem_subject_scheme":"Other"},{"subitem_subject":"nylon mesh","subitem_subject_scheme":"Other"},{"subitem_subject":"adsorption","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":"繊維状キレート剤を用いた酸性化汚泥からの重金属類の吸着除去および回収","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"繊維状キレート剤を用いた酸性化汚泥からの重金属類の吸着除去および回収"},{"subitem_title":"ADSORPTION AND RECOVERY OF HEAVY METALS FROM ACIDIFIED SLUDGE USING FIBROUS CHELATING AGENT","subitem_title_language":"en"}]},"item_type_id":"16","owner":"19","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-03-31"},"publish_date":"2023-03-31","publish_status":"0","recid":"15978","relation_version_is_last":true,"title":["繊維状キレート剤を用いた酸性化汚泥からの重金属類の吸着除去および回収"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-05-15T12:36:25.804843+00:00"}
