The pK_a value of fluorescein as an indicator in this method was spectroscopically found to be 6.67. In this method, the end point is difficult to discern owing to suppression of the acid dissociation of the indicator in titrated solution. The sensitivity and accuracy of coloration at the end point were evaluated in these methods using various buffer solutions to find means to enhance the accuracy of the Fajans method, the results indicating that the argentimetry in carbonate buffer solutions is most suitable for discernment of the equivalent point. The desired improvement has been achieved by adding sodium hydrogen carbonate at initial concentration of 0.01 mol/L. The experimental results in this method agreed well with those by the Mohr method in sensitivity of coloration and the equivalent point.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00053514","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"/////Laboratory of Pharmaceutical Analytical Chemistry, Gifu Pharmaceutical University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"/////岐阜薬科大学"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-06-30"}],"displaytype":"detail","filename":"KJ00000073615.pdf","filesize":[{"value":"454.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://gifu-pu.repo.nii.ac.jp/record/11237/files/KJ00000073615.pdf"},"version_id":"b1619e42-51c0-4971-a042-97f7c2f40ada"}]},"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_title":"<一般論文>日本薬局方収載Fajans法の改良","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<一般論文>日本薬局方収載Fajans法の改良"},{"subitem_title":"<Regular Article>Improvement of the Fajans Method Described in the Japanese Pharmacopoeia","subitem_title_language":"en"}]},"item_type_id":"1","owner":"5","path":["194"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-06-30"},"publish_date":"1998-06-30","publish_status":"0","recid":"11237","relation_version_is_last":true,"title":["<一般論文>日本薬局方収載Fajans法の改良"],"weko_creator_id":"5","weko_shared_id":5},"updated":"2023-06-19T08:37:54.960959+00:00"}
