It inevitably requires low working temperature, for example liquid nitrogen temperature. On the other hand, hydrogen isotopes are easily absorbed by palladium with considerable isotope effects at moderately high temperatures. This property is useful for gas chromatographic separation of hydrogen isotopes around room temperature. One problem of this application is the effects of supporting materials of Pd. The supporting materials often severely interfere with the isotope separation. In this study, Al2O3 was selected as a model of supporting materials. Its effect on the separation of hydrogen and deuterium from a 50%H2-50%D2 mixture gas was examined and compared with support-free Pd. Pd/Al2O3 packed columns showed very poor separation above room temperature, whereas considerably better results were obtained by the support-free Pd. Thermal desorption study on the adsorption and desorption of deuterium for those materials revealed that the Al2O3-supported acts as a sink of deuterium atoms spilled from the Pd surface by forming adsorbed water, HDO(a), and hydroxyl group, OD(a) with exchange reactions of residual H2O(a) and /or OH(a). As a consequence, the isotope effect on the adsorption or adsorption of hydrogen isotopes by Pd was obscured by isotope effects of the exchange reactions, leading to the poor separation. This study revealed the importance of hydrophilic supporting materials for the development of gas chromatographs for hydrogen isotope separation work at room temperature.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"59718","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kobayashi, Tohru"}]},{"nameIdentifiers":[{"nameIdentifier":"59719","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakamoto, Akira"}]},{"nameIdentifiers":[{"nameIdentifier":"59720","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Goto, Katsumi"}]},{"nameIdentifiers":[{"nameIdentifier":"59721","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Miyake, Hitoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"59722","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuyama, Masao"}]},{"nameIdentifiers":[{"nameIdentifier":"59723","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Kuniaki"}]}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00006411","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"富山大学水素同位体機能研究センター"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10443060","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8486","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂本, 章"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"後藤, 克己"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 均"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松山, 政夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 国昭"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"annual_report14-8.pdf","filesize":[{"value":"538.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"annual_report14-8.pdf","url":"https://toyama.repo.nii.ac.jp/record/6417/files/annual_report14-8.pdf"},"version_id":"7a7894b4-ef00-492c-aede-6a15202237e4"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"室温作動型水素同位体分離用　ガスクロマトグラフの開発（Ⅰ） －パラジウムの利用と担体の影響－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"室温作動型水素同位体分離用　ガスクロマトグラフの開発（Ⅰ） －パラジウムの利用と担体の影響－"}]},"item_type_id":"3","owner":"3","path":["793"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-03"},"publish_date":"2007-10-03","publish_status":"0","recid":"6417","relation_version_is_last":true,"title":["室温作動型水素同位体分離用　ガスクロマトグラフの開発（Ⅰ） －パラジウムの利用と担体の影響－"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T15:43:02.287190+00:00"}
