This method consists of the combination of the IEC on a cation exchange resin in the H+-form with UV-detection for determining NO3- and NO2- and the IEC on an anion exchange resin in the OH--form with coulometry-detection for determinig NH4+. These IEC systems are coupled with a \"delay coil tube\" (1 mm i. d. X 10 m long) to separate NH4+ peak from a \"ghost peak\" of cations such as Na+, K+, Mg2+, and Ca2+ caused by the imcomplete cation exchange reaction in the H+-form cation exchange resin column. The liquid chromatograph equiped with one delively pump (1 ml/min), dual sample injector (0.1 ml each), H+-cation exchange resin column (9 mm 1. d. x 110 mm long), OH--form anion exchange resin column (9 mm i. d. x 550 mm long)    UV detector (210 nm)    and flow coulometry detector (OH- detection) was used. The same sample solution is simultaneously injected onto each column with each sample loop, and chromatographed by the ion-exclusion. Only one kind of eluent (10% methanol-water) was used for the separation of NO3-, NO2-, and NH4+. The simultaneous determination of NO3-, NO2-, and NH4+ in the actual samples was accomplished within 30 min with satisfactory results.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"T106"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1982-12-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicPageEnd":"T112","bibliographicPageStart":"T106","bibliographicVolumeNumber":"31","bibliographic_titles":[{"bibliographic_title":"分析化学"},{"bibliographic_title":"分析化学"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"BunsekiKagaku_31-12_T106.pdf","filesize":[{"value":"455.4 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2011614/files/BunsekiKagaku_31-12_T106.pdf"},"version_id":"a5db112e-5d25-4ebd-a7d6-dc4e8aa6a58f"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"29594"},"item_title":"陽イオン及び陰イオン交換樹脂カラムを結合したイオン排除クロマトグラフ法による生物学的硝化-脱窒素処理工程水中の硝酸, 亜硝酸及びアンモニウムイオンの同時定量","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2011614","relation_version_is_last":true,"title":["陽イオン及び陰イオン交換樹脂カラムを結合したイオン排除クロマトグラフ法による生物学的硝化-脱窒素処理工程水中の硝酸, 亜硝酸及びアンモニウムイオンの同時定量"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T11:17:30.148683+00:00"}
