A 10-ml portion of sample water was put into a 50-ml Kjeldahl flask with 0.3g of mercury(II) sulfate and several pieces of boiling stone, and 25ml of the reagent-mixture was added. The solution was boiled at 160℃ for 30 min, setting a cooling finger inside the neck of the flask. The contents of the flask was transferred into a 50-ml measuring flask and was diluted with water to the mark. The absorbance of the solution was measured at the wavelength of 630nm with a 50-mm glass cell. Beer's law was obeyed over the range of 0〜1000ppm COD. The calibration curves using glycine, glucose, ethanol and starch, as the reference, gave their slope of 7.05×10^<-4> as the mean. Therefore, the COD value can be calculated from the following equation : GOD=absorbance/7.05×10^<-4>. An appropriate volume ratio of sulfuric add to phosphoric acid for the decomposition of glycine was found to be 3:2. The reaction time could be reduced to about one fourth of JIS(COD_<Cr>) method. The analytical results obtained for several kinds of industrial waste water are in good agreement with those obtained by JIS(COD_<Cr>) method.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理学部","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/110002907809/en/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 1978 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":"木羽, 敏泰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"寺田, 喜久雄"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"中川, 千枝"}],"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-TERADA-K-734.pdf","filesize":[{"value":"221.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-TERADA-K-734.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10334/files/SC-PR-TERADA-K-734.pdf"},"version_id":"c46e270f-cabe-4400-8bad-b7ed81e9ce37"}]},"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":"ニクロム酸カリウムを用いるCOD測定法の簡易化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ニクロム酸カリウムを用いるCOD測定法の簡易化"},{"subitem_title":"Simple chemical oxygen demand (COD) de-termination using dichromate","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":"10334","relation_version_is_last":true,"title":["ニクロム酸カリウムを用いるCOD測定法の簡易化"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:42:10.062991+00:00"}
