TPB is widely used as a precipitant of potassium and some monovalent metal ions and is known as an anionic surfactant. Surface tension was measured by the Shimadzu surface tensometer ST-1, which is based on the Wilhelmy method. Some quaternary ammonium cations which have strong surface activity were titrated directly with standard TPB solution. Potassium ion and some quaternary onium cations having small surface activity were back titrated as follows. To the sample solution was added an excess constant amount of TPB solution, the precipitate was removed by filtration, and then the excess TPB was titrated with a standard zephiramine (benzyldimethyltetradecylammonium chloride) solution. The end point showed good agreement with the color change of the titanium yellow adsorption indicator. This method is compared with argentimetric titration of the chloride ion in the quaternary onium salts. The F- and t-tests showed that there are no significant differences between the variances and means of the present and argentimetric titration methods.","subitem_description_type":"Abstract"}]},"item_1_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"9171","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kataoka, Masamitsu"}]},{"nameIdentifiers":[{"nameIdentifier":"9172","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kondoh, Yukihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"9173","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kambara, Tomihito"}]}]},"item_1_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_1_source_id_11":{"attribute_name":"書誌ID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_7":{"attribute_name":"ISSN / EISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"433","subitem_subject_scheme":"NDC"}]},"item_1_subject_17":{"attribute_name":"NIIサブジェクト","attribute_value_mlt":[{"subitem_subject":"化学","subitem_subject_scheme":"Other"}]},"item_1_version_type_15":{"attribute_name":"テキストバージョン","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":"片岡, 正光"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"近藤, 征弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神原, 富民"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-01-26"}],"displaytype":"detail","filename":"分析化学29(4)_225-228.pdf","filesize":[{"value":"303.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"分析化学29(4)_225-228.pdf","url":"https://barrel.repo.nii.ac.jp/record/4247/files/分析化学29(4)_225-228.pdf"},"version_id":"a3231799-1519-4667-b22c-c952fdd6593c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Potassium ion","subitem_subject_scheme":"Other"},{"subitem_subject":"Quaternary onium ions","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface tension titration","subitem_subject_scheme":"Other"},{"subitem_subject":"Tetraphenylborate","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"テトラフェニルホウ酸ナトリウム標準溶液による第4級オニウムイオンの表面張力滴定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テトラフェニルホウ酸ナトリウム標準溶液による第4級オニウムイオンの表面張力滴定"},{"subitem_title":"Surface tension titration of quaternary onium ions with the standard solution of sodium tetraphenylborate.","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["4"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-17"},"publish_date":"2012-05-17","publish_status":"0","recid":"4247","relation_version_is_last":true,"title":["テトラフェニルホウ酸ナトリウム標準溶液による第4級オニウムイオンの表面張力滴定"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-20T08:00:16.602093+00:00"}
