However, the geochemical and biogeochemical cycles of iodine are not sufficiently known. This is mainly due to the lack of analytical data on the iodine concentrations. We have developed analytical methods of iodine in geological and biological materials using ICP-MS and NAA. Iodine was at first separated from the sample by heating (1000-1100) and collected in TMAH (tetramethyl ammonium hydroxide) trap solution or activated charcoal (made from phenol resin). The trap solution was used for the determined of iodine by ICP-MS and activated charcoal was used for NAA.\nWe have analyzed iodine in various kinds of soil, sediments and rock samples and data were used to estimate the distribution and cycling of iodine in the environment. In addition to the determination of stable iodine, we have also analyzed\nI-129 (half-life: 16 Ma) in geochemical materials to study the levels and behavior of this nuclide in the environment.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"Third International Symposium on Nuclear Analytical Chemistry (NAC-III)","subitem_description_type":"Other"}]},"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":"Muramatsu, Yasuyuki"}],"nameIdentifiers":[{"nameIdentifier":"588654","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"588655","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村松 康行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"588656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 聡","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"588657","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Iodine analyses for geochemical materials: application to the study of the distribution and cycling of iodine in the environment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Iodine analyses for geochemical materials: application to the study of the distribution and cycling of iodine in the environment"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-06-07"},"publish_date":"2002-06-07","publish_status":"0","recid":"59102","relation_version_is_last":true,"title":["Iodine analyses for geochemical materials: application to the study of the distribution and cycling of iodine in the environment"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:08:42.352172+00:00"}
