In this work, four kinds of sieved shell samples: (a) “Ground original sample”, (b) “Heat-treatment ( 4 8 0 ∘ C , 6 hours) sample”, (c) “Heat-treatment ( 9 5 0 ∘ C , 6 hours) sample” and (d) “Heat-treatment ( 9 5 0 ∘ C , 6 hours) and water added sample” were used. Furthermore, to confirm the characteristics of the shell biomass, the crystal structure, the surface morphology, and the specific surface area of these shell samples were determined. Consequently, the following matters have been mainly clarified. (1) The crystal structure of the shell biomass was transformed from aragonite ( C a C O 3 ) into calcite ( C a C O 3 ) phase by heat-treatment ( 4 8 0 ∘ C , 6 hours); then mainly transformed into calcium oxide (CaO) by heat-treatment ( 9 5 0 ∘ C , 6 hours), and calcium hydroxide ( C a ( O H ) 2 ) by heat-treatment ( 9 5 0 ∘ C , 6 hours) and adding water. (2) The shell biomass showed excellent sorption capacity for lanthanides. (3) Adsorption isotherms using the shell biomass can be described by Langmuir and Freundlich isotherms satisfactorily for lanthanides except “heat-treatment ( 9 5 0 ∘ C , 6 hours) sample”. (4) Shell biomass (usually treated as waste material) can be an efficient sorbent for lanthanides in future.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Hindawi"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1155/2010/804854", "subitem_relation_type_select": "DOI"}}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12073437", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "15653633", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Koto, Yusuke"}], "nameIdentifiers": [{"nameIdentifier": "4278", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kano, Naoki"}], "nameIdentifiers": [{"nameIdentifier": "4279", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Wang, Yudan"}], "nameIdentifiers": [{"nameIdentifier": "4280", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sakamoto, Nobuo"}], "nameIdentifiers": [{"nameIdentifier": "4281", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Imaizumi, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "4282", "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": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2010_1-10.pdf", "filesize": [{"value": "4.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 4500000.0, "url": {"label": "2010_1-10.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1556/files/2010_1-10.pdf"}, "version_id": "d56a399f-556c-42eb-b35c-5f7f6e8db4e1"}]}, "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": "Biosorption of lanthanides from Aqueous Solutions using Pretreated Buccinum tenuissimum Shell Biomass", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Biosorption of lanthanides from Aqueous Solutions using Pretreated Buccinum tenuissimum Shell Biomass"}, {"subitem_title": "Biosorption of lanthanides from Aqueous Solutions using Pretreated Buccinum tenuissimum Shell Biomass", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/21903", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-04-18"}, "publish_date": "2013-04-18", "publish_status": "0", "recid": "1556", "relation": {}, "relation_version_is_last": true, "title": ["Biosorption of lanthanides from Aqueous Solutions using Pretreated Buccinum tenuissimum Shell Biomass"], "weko_shared_id": null}
