Removal efficiency more than ca. 90% was obtained for metals of chromium, copper, iron and zinc, while that of manganese (Mn) was only ca. 50%. Therefore, in the present study, a combined method of flocculation and coprecipitation with iron hydroxide was attempted to increase the removal efficiency of Mn. An ion exchange method was also applied for a comparison. For the combined method of flocculation and coprecipitation, the removal efficiency of almost 100% was accomplished at the wide pH range from 7 to 12, although that value decreased negligibly at pH 6. On the other hand, for the ion exchange method, the removal efficiency became higher as pH became lower. The maximum value (93%) was obtained at pH 3. The combined method of flocculation and coprecipitation was found to be useful for removing Mn in wastewater.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00001550","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00010431","subitem_relation_type_select":"NCID"}}]},"item_10002_version_type_20":{"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":"田中, 智一"}],"nameIdentifiers":[{"nameIdentifier":"14558","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"五十嵐, 雅明"}],"nameIdentifiers":[{"nameIdentifier":"14559","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Tomokazu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14560","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Igarashi, Masaaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14561","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":"2023-04-12"}],"displaytype":"detail","filename":"268-271.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"268-271.pdf","url":"https://fut.repo.nii.ac.jp/record/1556/files/268-271.pdf"},"version_id":"5828c152-d202-4cae-a99f-23119aa4299c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Heavy Metal","subitem_subject_scheme":"Other"},{"subitem_subject":"Flocculation","subitem_subject_scheme":"Other"},{"subitem_subject":"Coprecipitation","subitem_subject_scheme":"Other"},{"subitem_subject":"Wastewater","subitem_subject_scheme":"Other"},{"subitem_subject":"Polyglutamic Acid","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ポリグルタミン酸を凝集剤に用いる廃水中の重金属の分離除去","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポリグルタミン酸を凝集剤に用いる廃水中の重金属の分離除去"},{"subitem_title":"Removal of Heavy Metals inWastewater with Polyglutamic Acid as a Flocculating Agent","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-06"},"publish_date":"2015-08-06","publish_status":"0","recid":"1556","relation_version_is_last":true,"title":["ポリグルタミン酸を凝集剤に用いる廃水中の重金属の分離除去"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:11:47.727911+00:00"}
