The method involves eluting mercury species from the soil/sediment samples using 5 M HCl containing 5 mM Pd2+ and 0.1 M Cu2+ and then extracting MeHg+ and EtHg+ into toluene as chlorides. These alkylmercury chlorides are then back-extracted into an aqueous EDTA solution, creating EDTA complexes. Finally, an emetine-dithiocarbamate (emetineCS2) solution is added to the EDTA solution to form emetineCS2–alkylmercury complexes. EmetineCS2–MeHg and emetineCS2–EtHg were separated using reverse-phase HPLC and then detected by the chemiluminescence reaction with tris(2,2′-bipyridine)ruthenium(III). The MeHg+ and EtHg+ calibration curves, using the peak height, were linear from 0.5 to 20 ng (as Hg). The detection limit was 0.16 ng/g (analyzing 1 g soil or sediment). The procedure was validated by analyzing a certified reference material (ERM CC580, estuarine sediment). The MeHg+ concentration determined using the proposed method was in good agreement with the certified value, and EtHg+ was detected in the reference material. A preliminary study of the relationship between environmental mercury concentrations and MeHg+ production was performed.","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":"Elsevier","subitem_publisher_language":"en"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.chroma.2013.02.004","subitem_relation_type_select":"DOI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Elsevier","subitem_rights_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00219673","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10985833","subitem_source_identifier_type":"NCID"}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kodamatani, Hitoshi","creatorNameLang":"en"},{"creatorName":"コダマタニ, ヒトシ","creatorNameLang":"ja-Kana"},{"creatorName":"児玉谷, 仁","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomiyasu, Takashi","creatorNameLang":"en"},{"creatorName":"トミヤス, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"冨安, 卓滋","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"KODAMATANI_Journal of Chromatography A_2013.pdf","filesize":[{"value":"439.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KODAMATANI_Journal of Chromatography A_2013.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/5507/files/KODAMATANI_Journal of Chromatography A_2013.pdf"},"version_id":"f5ffc6e9-b065-4ed7-a842-8723f8958202"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Methylmercury","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ethylmercury","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"HPLC","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Chemiluminescence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Soil","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sediment","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Selective determination method for measurement of methylmercury and ethylmercury in soil/sediment samples using high-performance liquid chromatography–chemiluminescence detection coupled with simple extraction technique","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Selective determination method for measurement of methylmercury and ethylmercury in soil/sediment samples using high-performance liquid chromatography–chemiluminescence detection coupled with simple extraction technique","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["92"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-07-01"},"publish_date":"2013-07-01","publish_status":"0","recid":"5507","relation_version_is_last":true,"title":["Selective determination method for measurement of methylmercury and ethylmercury in soil/sediment samples using high-performance liquid chromatography–chemiluminescence detection coupled with simple extraction technique"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T07:06:47.928710+00:00"}
