In the developed methodology, a suspension of GO was injected into uranium‐spiked multielement solutions including rubidium; after filtration, the membrane filter with collected GO was placed in a small volume of internal standard acid solution and the eluent containing uranium was deposited onto a fluorine resin‐ coated slide glass, which is a disposable sample stage. Using GO was effective for removal of rubidium from the measurement solution to avoid interference between Rb Kα peak and U Lα peak. The high enrichment factor of 150 enables obtaining uranium detection limits of 0.042, 0.087, and 0.12 μg L−1 for ionic strength of 0.01, 0.1, and 1 mol L−1, respectively. Such low detection limits were obtained by using a benchtop TXRF spectrometer with 5‐min measurement. The proposed method is suitable for trace uranium determination in water, including high salinity samples.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/xrs.3032","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://onlinelibrary.wiley.com/doi/abs/10.1002/xrs.3032","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0049-8246","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takahashi, Hiroaki"}],"nameIdentifiers":[{"nameIdentifier":"997538","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Izumoto, Yukie"}],"nameIdentifiers":[{"nameIdentifier":"997539","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuyama, Tsugufumi"}],"nameIdentifiers":[{"nameIdentifier":"997540","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshii, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"997541","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yukie, Izumoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997542","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsugufumi, Matsuyama","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997543","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroshi, Yoshii","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"997544","nameIdentifierScheme":"WEKO"}]}]},"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":"Trace determination of uranium preconcentrated using graphene oxide by total reflection X‐ray fluorescence spectrometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trace determination of uranium preconcentrated using graphene oxide by total reflection X‐ray fluorescence spectrometry"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-09-17"},"publish_date":"2019-09-17","publish_status":"0","recid":"76800","relation_version_is_last":true,"title":["Trace determination of uranium preconcentrated using graphene oxide by total reflection X‐ray fluorescence spectrometry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:52:37.091805+00:00"}
