The experimental results suggested that the anodically generated bromine (Br-2) would be hydrolyzed to hypobromous acid (HBrO) at the pH range of 5 - 7 and was further disproportionate to hypobromite anion (BrO-) when pH was larger than 7. Both HBrO and BrO- were confirmed to be participated in the following homogeneous chemical reaction with the coexisted ammonium ion. However, HBrO is electroactive whereas BrO- is electroinactive at carbon electrode. Based upon the reaction of HBrO with NH4+, an indirect electrochemical method was proposed for determination of NH4+ with dual-electrode configuration in phosphate buffer solution (pH 7), where HBrO was produced at a generator electrode and the excess HBrO was subsequently detected at a collector electrode after a reaction with NH4+ in a batch solution or in a micro flow injection analytical (micro-FIA) system by using an interdigitated array (IDA) Pt microelectrode and a carbon film ring-disk electrode (CFRDE), respectively. The decreasing of reduction current at the collector electrode was proportional to the concentration NH4+ in both systems, with the detection limit below 3.0 mu M. This approach shows the advantage of highly selectivity even in presence of a large amount of coexisted cations, and was successfully applied for the determination of NH4+ in environmental water samples."}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Takahashi, M"}], "nameIdentifiers": [{"nameIdentifier": "36533", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, K"}], "nameIdentifiers": [{"nameIdentifier": "36534", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Jin, J"}], "nameIdentifiers": [{"nameIdentifier": "36535", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Study_on_the_Indirect.pdf", "filesize": [{"value": "558.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 558500.0, "url": {"label": "Study_on_the_Indirect.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/11924/files/Study_on_the_Indirect.pdf"}, "version_id": "3966778e-bc26-432a-894a-58d64eb044bb"}]}, "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": "Study on the Indirect Electrochemical Detection of Ammonium Ion with In Situ Electrogenerated Hypobromous Acid", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Study on the Indirect Electrochemical Detection of Ammonium Ion with In Situ Electrogenerated Hypobromous Acid", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["1170"], "permalink_uri": "http://hdl.handle.net/10091/3033", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-05-15"}, "publish_date": "2009-05-15", "publish_status": "0", "recid": "11924", "relation": {}, "relation_version_is_last": true, "title": ["Study on the Indirect Electrochemical Detection of Ammonium Ion with In Situ Electrogenerated Hypobromous Acid"], "weko_shared_id": -1}
