Removal of arsenic from aquatic environment is an active issue all over the world. Adsorption process receives major attention due to its low cost, simplicity, high efficiency, easy regeneration of sorbents and easy handling. In the present work, adsorptive removal of As（III） and As（V） was investigated using three kinds of adsorbents, Diaion-CRB05 with N-methylglucamine group as a functional group, Lewatit-FO36, and AMAs （Goethite） with FeO（OH） group. Batch adsorption of arsenic indicates that adsorption is affected by pH, and the optimal pH range is 3.0 – 4.5 for As（V） and 7.0 – 9.0 for As（III）. Adsorption isotherms of both As（III） and As（V） are of Langmuir mechanism, and LewatitFO36 is revealed to possess the highest adsorption capacities for both As（V） （122 mg/g） and As（III） （98.0 mg/g）. Desorption of the loaded arsenic from all of adsorbents could be performed by either diluted HCl or NaOH solution. Column studies for the arsenic removal indicated that Lewatit FO36 was effectively performed to remove As（V） until bed volume of 820.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10010_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"University of Miyazaki, IRISH","subitem_publisher_language":"en"}]},"item_10010_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":"Anh, Viet  HOANG","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"32230","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshizuka, Kazuharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"32231","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishihama, Syouhei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"32232","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":"2020-06-22"}],"displaytype":"detail","filename":"5th_int_p8.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://miyazaki-u.repo.nii.ac.jp/record/6043/files/5th_int_p8.pdf"},"version_id":"c62a37cd-b7b3-4cd3-9725-189e38ff7ea0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Arsenic, Lewatit FO36, CRB05, AMAs, Adsorption","subitem_subject_language":"en","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":"other","resourceuri":"http://purl.org/coar/resource_type/c_1843"}]},"item_title":"Adsorptive Removal of Arsenic from Aquatic Environment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Adsorptive Removal of Arsenic from Aquatic Environment","subitem_title_language":"en"}]},"item_type_id":"10010","owner":"5","path":["80","65"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-06-22"},"publish_date":"2020-06-22","publish_status":"0","recid":"6043","relation_version_is_last":true,"title":["Adsorptive Removal of Arsenic from Aquatic Environment"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-07-29T11:22:36.485515+00:00"}
