Firstly, the extraction of mercury species from biological samples was studied, and it was found that 2-mercaptoethanol (2-ME), which has a mercapto group, was an effective extractant. For three certified reference materials, which have the certified values of the CH3Hg＋\nconcentration, extraction by a 2-ME solution and the HPLC-UV-CVAFS measurement were\ncarried out. It was confirmed that the measured values were about the same as the certified values. The same analytical method was applied to real seafood samples. The sum of the CH3Hg＋ concentration and the Hg2＋ concentration in the extraction solution, which was obtained by the HPLC-UV-CVAFS measurement, was about the same as the total mercury concentration obtained by the heat vaporization atomic absorption spectrometry (HVAAS) measurement. Therefore, it is evident that the fractional determination of mercury species in biological samples was favorably performed when the extraction solution obtained by the 2-ME extraction was analyzed by HPLC-UV-CVAFS.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人日本分析化学会","subitem_publisher_language":"ja"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2116/bunsekikagaku.61.1073","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"PISSN"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"433","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"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":"林, 健太郎","creatorNameLang":"ja"},{"creatorName":"ハヤシ, ケンタロウ","creatorNameLang":"ja-Kana"},{"creatorName":"Hayashi, Kentaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大迫, 譲滋","creatorNameLang":"ja"},{"creatorName":"オオサコ, ジョウジ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohsako, Joji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中島, 常憲","creatorNameLang":"ja"},{"creatorName":"ナカジマ, ツネノリ","creatorNameLang":"ja-Kana"},{"creatorName":"Nakajima, Tsunenori","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"高梨, 啓和","creatorNameLang":"ja"},{"creatorName":"タカナシ, ヒロカズ","creatorNameLang":"ja-Kana"},{"creatorName":"Takanashi, Hirokazu","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"大木, 章","creatorNameLang":"ja"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"Fractional Determination of Mercury Species in Biological Samples by Use of HPLC and Cold Vapor Atomic Fluorescence Spectrometry.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Fractional Determination of Mercury Species in Biological Samples by Use of HPLC and Cold Vapor Atomic Fluorescence Spectrometry.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/2818/files/Fractional Determination of Mercury Species in Biological Samples by Use of HPLC and Cold Vapor Atomic Fluorescence Spectrometry.pdf"},"version_id":"7c396254-54de-4fc0-8048-c3398b6e01e3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fractional determination","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mercury","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"biological samples","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"HPLC","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cold vapor atomic","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"HPLCと冷蒸気原子蛍光分析を用いる生物試料中の水銀種分別定量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"HPLCと冷蒸気原子蛍光分析を用いる生物試料中の水銀種分別定量","subitem_title_language":"ja"},{"subitem_title":"Fractional Determination of Mercury Species in Biological Samples by","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["92"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-05"},"publish_date":"2015-06-05","publish_status":"0","recid":"2818","relation_version_is_last":true,"title":["HPLCと冷蒸気原子蛍光分析を用いる生物試料中の水銀種分別定量"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T07:03:11.959680+00:00"}
