To the soil absorbed Cd, phosphate and ammonium, the extraction by three solution (0.01M-HC1, 0.01M-KC1 and water) was carried out successively. The mutual relationships of components in the extracted solution were discussed. These results are summarized as fellow: The treatment of diammonium phosphate to the Cd absorbed soil clearly depressed the dissolution of absorbed Cd by every kind of extracted solution. Relation between phosphate, ammonium and cadmium ion in each extracted solution of the used soil did not indicate lack of a unified tendency. In the no phosphate treatment to each soil as well as the treatment of diammonium phosphate, the humus content in soil had a great influence of the Cd absorbed strength by soil. In the less humus content soil, regardless of less dissoluble phosphate of each extract, a large quantity of dissoluble Cd from the phosphate treated soil had been observed. These results were suggested that the phosphate treatment to the soil directly did not take part in absorption of Cd by soil. Dissoluble Cd contents from soil are closely related with the pH of each extracted solution. There are most contents of Cd at the region of low pH values of every used soil, and its contents reduced rapidly with the consequence of higher pH region of extracted solution. The least Cd contents were exhibited at pH 6～7. In the treatment of diammonium phosphate solution to the Cd absorbed soil, the pH values of the each extracted solution preserved higher pH region. Therefore, insolubility of absorbed Cd by soil seemed to rely upon higher buffering action of the soil.[著者抄録]本研究は,上壌のCd吸収におけるリン酸の関与を明らかにする目的でCd,リン酸,アンモニウムを吸収させた上壌に対して,3種類の溶液により連続抽出を行ない,溶出成分の相互の開通を検討したものである。得られた結果は以下のようである。Cd吸収上壌へのリン酸ニアンモニウム処理は,吸収Cdの溶出をいずれの通続溶出液操作に対しても明らかに抑制した。各抽出溶液中のリン酸,アンモニウムとCdの関係は供試した各土壌に対して一定の傾向が認められない場合が多い。土壌中の腐植含量は,無処理区はもちろんリン酸ニアンモニウム処理区においても,Cdの土壌吸収力に大きな影響をもたらした。腐植含量の少ない土壌は,著るしいリン酸の溶出が認められないにもかかわらず,吸収Cdの溶出が顕著に認められた。これらの結果はリン酸が直接関与しないCdの吸収を暗示した。吸収Cdの溶出量は,溶出平衡液のpHと密接であり,各土壌とも強酸性域で多く,中性に近づくにしたがい急減し,pH6～7附近で最低値を示した。リン酸ニアンモニウム処理区は,溶出平衡液のpHを高く維持した。そのために吸収Cdの不溶化は土壌の緩衝能に強く依存するものと考えられる。","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学農学部"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04538889","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nakajima, Teruo"},{"subitem_text_language":"en","subitem_text_value":"Kawamura, Saburo"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部農芸化学科土壌学研究室"},{"subitem_text_value":"近畿大学農学部農芸化学科土壌学研究室"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Laboratory of Soil Science, Department of Agricultural Chemistry, Faculty of Agriculture, Kinki University"},{"subitem_text_value":"Laboratory of Soil Science, Department of Agricultural Chemistry, Faculty of Agriculture, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中島,  照夫"},{"creatorName":"ナカジマ, テルオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川村,  三郎"},{"creatorName":"カワムラ, サブロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AN00064044-19780315-0033.pdf","filesize":[{"value":"851.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00064044-19780315-0033.pdf","url":"https://kindai.repo.nii.ac.jp/record/5121/files/AN00064044-19780315-0033.pdf"},"version_id":"f66420f4-d1c9-48be-9aae-0ade4e0edad3"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_thumbnail":{"attribute_name":"サムネイル","attribute_value_mlt":[{"subitem_thumbnail":[{"thumbnail_label":"AN00064044-19780315-0033.jpeg","thumbnail_url":"/api/files/b194bea0-3bb0-4233-9ad5-eb7048fd296d/AN00064044-19780315-0033.jpeg?versionId=c73f40d0-1f68-486a-a538-f7f74cd23fab"}]}]},"item_title":"リン酸二アンモニウム処理によって土壌に吸収させたCdの溶出と吸収Cd形態の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リン酸二アンモニウム処理によって土壌に吸収させたCdの溶出と吸収Cd形態の関係"},{"subitem_title":"On the Relation with Cd Forms in Soil and Cd Dissolution from Soil Which Treated with Diammonium Phosphate","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["1455","3070"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-28"},"publish_date":"2008-01-28","publish_status":"0","recid":"5121","relation_version_is_last":true,"title":["リン酸二アンモニウム処理によって土壌に吸収させたCdの溶出と吸収Cd形態の関係"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:34:02.410042+00:00"}
