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", "download_preview_message": "", "file_order": 0, "filename": "22_12_1519-1524.pdf", "filesize": [{"value": "118.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 118600.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/29853", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2014-09-10"}, "publish_date": "2014-09-10", "publish_status": "0", "recid": "1508", "relation": {}, "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_shared_id": -1}
