Then, bismuth was determined by atomic absorption spectrometry with hydride generation in the sensitivity of 0.1 mug l ^<-1>. The mini-column filled with the thionalide-SG (0.1 g) was introduced in a flow injection system. After 15 ml of a sample solution was flowed in the column, 2 M hydrochloric acid containing 5% thiourea was passed through the column and then the absorbance of the Bi-complex was measured by the use of a flow cell.\nPoly(chlorotrifluoroethylene) resin adsorbed some metal complexes, such as Cu, Cd, Fe(III), and Zn-8-quinolinolates at pH3-6. The complexes or metals were eluted with methanol or 0.1 M hydrochloric acid. On the other hand, Cu(II)- 8-quinolinol sulfonate was adsorbed on the resin as an ion-associated complex with tetrabutylammonium cation. The adsorbability seems to increase with the increase of hydrophobic inter- action between the resin and complexes. By the use of these properties, preconcentration of copper from a sample solution added with 8-quinoli- nol sulfonate and tetrabutylammonium cation.\nCS_2 was introduced in chitin by the simple method. The chitin-CS_2 quantitatively adsorbed ^<99m> Tc at pH<less than or equal>2.0 by the column method. It was assumed that technetium was reduced to low valence state with CS_2 and formed a complex with S-atom. The direct elution of ^<99m>Tc was seemed to be difficult, however, above 98% of the element could be eluted by heating the chitin-CS_2 retaining ^<99m>Tc in 1 M sulfuric acid containing 0.5 g of peroxodisulfate for 10 min.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:63470028, 研究期間(年度):1988 – 1989","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「各種吸着体を用いる超微量金属元素の分離濃縮及びキャラクタリゼ-ション」課題番号63470028\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-63470028/634700281989kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00067592","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=50019460"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=50019460","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-63470028/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-63470028/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-63470028/634700281989kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-63470028/634700281989kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-11-07"}],"displaytype":"detail","filename":"SC-PR-TERADA-K-kaken 1993-2p.pdf","filesize":[{"value":"123.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TERADA-K-kaken 1993-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/61349/files/SC-PR-TERADA-K-kaken 1993-2p.pdf"},"version_id":"87a6b2a8-1850-4ad5-bc80-323d0078297e"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"各種吸着体を用いる超微量金属元素の分離濃縮及びキャラクタリゼ-ション","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"各種吸着体を用いる超微量金属元素の分離濃縮及びキャラクタリゼ-ション"},{"subitem_title":"Preconcentration and Characterization of Trace Metals by the Use of Various Absorbents","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2844"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-11-07"},"publish_date":"2022-11-07","publish_status":"0","recid":"61349","relation_version_is_last":true,"title":["各種吸着体を用いる超微量金属元素の分離濃縮及びキャラクタリゼ-ション"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:47:12.332575+00:00"}
