It was found that the Kd-Se values, ranged from 12 to 1060 (arithmetic mean =315), were highly correlated to the soil active-aluminum (Al) and active-iron (Fe) contents. Those two components were considered to be the major adsorbents of Se in Japanese soils. The mechanism of Se adsorption by the active-Al and active-Fe is regarded to be ligand-exchange, which is the same adsorption mechanism for phosphorus (P). Therefore, using a modified sequential extraction procedure proposed for soil adsorbed P, the adsorbed Se-75 was extracted from 12 selected soil samples. In this procedure, we employed 1 mol/L NH4Cl, 4 mol/L NH4F and 0.1 mol/L NaOH for extracting loosely bound Se, active-Al bound Se and active-Fe bound Se, respectively. The results showed that 80-100% of the adsorbed Se was recovered as active-Al and active-Fe bound forms. The loosely bound Se was less than 2% of the total amount of Se sorbed on each soil. The active-Al bound Se was the dominant form in the soils that had higher Kd values, while the active-Fe bound Se was the dominant form in the soils that had lower Kd values. Therefore, we considered that the higher values of Kd-Se were mainly caused by the sorption on active-Al.","subitem_description_type":"Abstract"}]},"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":"Nakamaru, Yasuo"}],"nameIdentifiers":[{"nameIdentifier":"547813","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"547814","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"547815","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中丸 康夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"547816","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"547817","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"547818","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Using a sequential extraction procedure for selective determination of soil-adsorbed Se","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Using a sequential extraction procedure for selective determination of soil-adsorbed Se"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-05"},"publish_date":"2006-06-05","publish_status":"0","recid":"53673","relation_version_is_last":true,"title":["Using a sequential extraction procedure for selective determination of soil-adsorbed Se"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:09:56.094512+00:00"}
