The application of this material for water treatment has not yet been developed. Herein, fullerenes-extracted soot in the form of powder containing amino groups was prepared by reacting the soot with ethylenediamine, and was used as an adsorbent of hexavalent chromium [Cr(VI)] for removing Cr(VI) from aqueous solutions; this removal was studied by batch adsorption experiments. The effect of experimental parameters such as the pH, initial Cr(VI) concentration, and agitation time on the adsorption process was investigated. The adsorption of Cr(VI) was highly pH-dependent and the optimal pH for the adsorption process was 3.0. The data of Cr(VI) adsorption by fullerenes-extracted soot modified with ethylenediamine (FES-ED) fit the Langmuir isotherm equation well. The maximum Cr(VI)-uptake capacity of FES-ED was 93 mg g−1. The desorption of Cr(VI) from the adsorbent was also studied. The adsorbed Cr(VI) was eluted with 20 mL of an aqueous solution with pH 12 and the percentage recovery of Cr(VI) was determined as 75%. The adsorption and desorption test using the same FES-ED powder was repeated in triplicate to examine the reusability of the adsorbent. The adsorption was 97% and the desorption was \u003e70% through the adsorption–desorption cycles. The adsorption of methyl orange onto the FES-ED was also examined. The dye was almost quantitatively removed from the aqueous solution by the adsorbent (the initial concentration of methyl orange: 40 μg mL−1; the adsorbent added: 10 mg/40 mL). Thus, we concluded that the FES-ED can be used as a novel adsorbent for removing pollutants from water.", "subitem_description_type": "Abstract"}]}, "item_6_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_6_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "Journal of Environmental Chemical Engineering. 2(2):1191-1198 (2014)", "subitem_description_type": "Other"}]}, "item_6_link_3": {"attribute_name": "信州大学研究者総覧へのリンク", "attribute_value_mlt": [{"subitem_link_text": "Moriwaki, Hiroshi", "subitem_link_url": "http://soar-rd.shinshu-u.ac.jp/profile/ja.jCyFjFkV.html"}]}, "item_6_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "ELSEVIER"}]}, "item_6_relation_48": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1016/j.jece.2014.05.003"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.jece.2014.05.003", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_62": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright© 2014 Elsevier"}]}, "item_6_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_6_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2213-3437", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2213-3437", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Nakagawa,  Takahiro"}], "nameIdentifiers": [{"nameIdentifier": "40428", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kokubo,  Ken"}], "nameIdentifiers": [{"nameIdentifier": "40429", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriwaki,  Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "40430", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Application_fullerenes-extracted_soot_modified.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "Application_fullerenes-extracted_soot_modified.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/13333/files/Application_fullerenes-extracted_soot_modified.pdf"}, "version_id": "39d1cc2c-be88-4f98-9a1d-d0da2fdc735c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Fullerenes-extracted soot", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ethylenediamine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cr(VI)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Adsorption", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cleanup technology", "subitem_subject_scheme": "Other"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Application of fullerenes-extracted soot modified with ethylenediamine as a novel adsorbent of hexavalent chromium in water", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Application of fullerenes-extracted soot modified with ethylenediamine as a novel adsorbent of hexavalent chromium in water", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["1310"], "permalink_uri": "http://hdl.handle.net/10091/17746", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2014-07-23"}, "publish_date": "2014-07-23", "publish_status": "0", "recid": "13333", "relation": {}, "relation_version_is_last": true, "title": ["Application of fullerenes-extracted soot modified with ethylenediamine as a novel adsorbent of hexavalent chromium in water"], "weko_shared_id": -1}
