In this study, a new chemical separation method was developed for rapid determination of Pu in soil and sediment samples, based on the following investigations: extraction behaviors of interfering elements (IEs, for ICPMS measurement) on TEVA resin; decontamination of U using TEVA, UTEVA and DGA resins and the impact of co-precipitation on Pu determination. The developed method consists of four steps: HNO3 leaching for Pu release; CaF2/LaF3 co-precipitation for the removal of major metals and U; the proposed TEVA+UTEVA+DGA procedure for the removal of U, Pb, Bi, Tl, Hg, Hf, Pt and Dy; and ICPMS measurement. The accuracy of this method in determining 239+240Pu activity and 239Pu/240Pu and 241Pu/239Pu atom ratios was validated by analyzing five standard reference materials (soil, fresh water sediment and ocean sediment). This method is characterized by its stable and high Pu recovery (90-97% for soil; 92-98% for sediment) and high decontamination factor of U (1.6 × 107) which is the highest reported for soil and sediment samples. In addition, the short analytical time of 12 h and the method detection limits, which are the lowest yet reported in literature, of 0.56 μBq g-1 for 239Pu, 1.2 μBq g-1 for 240Pu, and 0.34 mBq g-1 for 241Pu (calculated on the basis of a 1 g soil sample) allow the rapid determination of ultratrace level Pu in soil and sediment samples.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ACS Publications"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/acs.analchem.6b04975.","subitem_relation_type_select":"DOI"}}]},"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":"Wang, Zhongtang"}],"nameIdentifiers":[{"nameIdentifier":"480219","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"480220","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ni, Youyi"}],"nameIdentifiers":[{"nameIdentifier":"480221","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Men, Wu"}],"nameIdentifiers":[{"nameIdentifier":"480222","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"480223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"480224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"王 鍾堂","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"倪 有意","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"門 武","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480228","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480230","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":"High performance method for determination of Pu isotopes in soil and sediment samples by sector field inductively coupled plasma mass spectrometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High performance method for determination of Pu isotopes in soil and sediment samples by sector field inductively coupled plasma mass spectrometry"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-26"},"publish_date":"2017-04-26","publish_status":"0","recid":"47839","relation_version_is_last":true,"title":["High performance method for determination of Pu isotopes in soil and sediment samples by sector field inductively coupled plasma mass spectrometry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:34:57.873640+00:00"}
