This method was successfully applied to the determination of the total Cr concentration by flow injection-solid phase spectrophotometry using diphenylcarbazide as a coloring agent. With the applied potential of 1.35 V (vs. Ag/AgCl) and the flow rate of 0.80 cm3 min-1, Cr(III) was quantitatively oxidized to Cr(VI) at room temperature. The total Cr concentration of sub-µg dm-3 in 3 - 4 samples could be determined within 1 h using an aqueous sample volume of 7.1 cm3. The analytical values of the total Cr concentration in natural water were in good agreement with those obtained by ICP-MS. The detection limit of the proposed method was 0.014 µg dm-3 (3σ, n = 7). This method could be applied to the specific determination of Cr(III) and Cr(VI) in river water samples.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会","subitem_publisher_language":"ja"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.2116/analsci.22.1519","subitem_relation_type_select":"DOI"}}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10500785","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0910-6340","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Matsuoka, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakatsu, Yu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takehara, Ko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saputro, Sulistyo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshimura, Kazuhisa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4087","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"22_12_1519-1524.pdf","filesize":[{"value":"118.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"22_12_1519-1524.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1508/files/22_12_1519-1524.pdf"},"version_id":"06fa5e93-a35e-4c6d-9fed-e68f6aa51d7c"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"On-line Electrochemical Oxidation of Cr(III) for the Determination of Total Cr by Flow Injection-Solid Phase Spectrophotometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On-line Electrochemical Oxidation of Cr(III) for the Determination of Total Cr by Flow Injection-Solid Phase Spectrophotometry","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-09-10"},"publish_date":"2014-09-10","publish_status":"0","recid":"1508","relation_version_is_last":true,"title":["On-line Electrochemical Oxidation of Cr(III) for the Determination of Total Cr by Flow Injection-Solid Phase Spectrophotometry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T03:34:15.102006+00:00"}
