The improved method is developed for the usual mecury determination by cold-vapor AAS with acidic tin (II) after digestion of the sample. In the Japanese official method, iodide and its related compounds interfered with the trace mercury determination. Hence, the improvement of the official method is necessary for complicated environmental samples such as waste waters from university laboratories. The determination procedures are as follows : An aliquot (less than 100ml) of sample solution is taken into a reaction vessel after digestion with potassium peroxodisulfate in a diluted sulfuric acid solution heated at 95℃ for 1h. To the solution, 10ml of 5M sodium hydroxide, 2ml of 1000mg/1 Cu^<2+> solution, 10ml of 5% potassium zinc cyanide solution, and 2ml of 10% tin (II) chloride solution are added, and the evolved mercury is measured with an atomic absorption spectrometer at 253.7nm. The reducing power of tin (II) in alkaline solution is stronger than that in acidic solution because the standard redox potential for tin (II) is-0.93V vs. NHE at pH 14 (0.15V vs. NHE in acidic). However, potassium zinc cyanide is added as a masking agent for silver (I) ion because it interferes with the improved alkaline method. The detection limit and precision of the improved method are 0.5μg/l and 3%, respectively. The method was applied to the determination of mercury in waste water samples containing iodide with satisfactory results.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Analytical Chemistry = 日本分析化学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.or.jp/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002909579/en/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 1987 日本分析化学会"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"伊永, 隆史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 悦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"原, 由美子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂元, 隼雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"丁子, 哲治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中川, 千枝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井勝, 久喜"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊沢, 美代子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"後藤, 正志"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-NAKAGAWA-C-194.pdf","filesize":[{"value":"407.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-NAKAGAWA-C-194.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/11068/files/SC-PR-NAKAGAWA-C-194.pdf"},"version_id":"07eedb07-2884-4ae8-a027-c787a6d98386"}]},"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":"還元気化原子吸光法による水銀分析におけるヨウ化物の干渉とその除去-改良法(<特集>環境汚染物質の分析化学)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"還元気化原子吸光法による水銀分析におけるヨウ化物の干渉とその除去-改良法(<特集>環境汚染物質の分析化学)"},{"subitem_title":"Elimination of interference by iodide in determination of mercury by cold-vapor AAS.(<Special Articles>Analytical Chemistry on Environmental Pollutants)","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"11068","relation_version_is_last":true,"title":["還元気化原子吸光法による水銀分析におけるヨウ化物の干渉とその除去-改良法(<特集>環境汚染物質の分析化学)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:33:28.050767+00:00"}
