Fulvic acids were extracted from 4 soils which derived under oxidative or reductive conditions. All fulvic acid desalted with ion exchanger, was separated on Sephadex G-25 gels with N-KCl as eluant into two fractions with distribution coefficient (Kd) of 0 and approximately 0.6,respectively. The larger molecular weight fraction, minor fraction, had a molecular weight in the range of 5000 or higher, and the smaller, major fraction, had a molecular weight in the range from 700 to 5000. The former fraction contained some components which was rich in reductive end group. To determine the affinity between fulvic acids and metal ions, fulvic acid solution containing metal ions adjusted to pH 5-6,was eluted on Sephadex G-25 by the same way. The results showed that only the low molecular fraction could react with metal ions, and the strength order of affinity were Cu>Zn>Mn. By infrared spectroscopy, it was concluded that the reaction was the chelation which the COOH group, as rigand, of fulvic acids coordinated to metal ions. The affinity of fulvic acids extracted from the soils which derived under oxidative condition were stronger than that under reductive condition. And it was estimated that the differences of the affinity depended on the COOH contents of fulvic acids. The results presented in this paper show that the Sephadex gel filtration is a promising technique for studying the reactions of fulvic acids with metal ions.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 秀和","creatorNameLang":"ja"},{"creatorName":"ヤマダ, ヒデカズ","creatorNameLang":"ja-Kana"},{"creatorName":"Yamada, Hidekazu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"米林, 甲陽","creatorNameLang":"ja"},{"creatorName":"ヨネバヤシ, コウヨウ","creatorNameLang":"ja-Kana"},{"creatorName":"Yonebayashi, Koyo","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"服部, 共生","creatorNameLang":"ja"},{"creatorName":"ハットリ, トモオ","creatorNameLang":"ja-Kana"},{"creatorName":"Hattori, Tomoo","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"森田, 修二","creatorNameLang":"ja"},{"creatorName":"モリタ, シュウジ","creatorNameLang":"ja-Kana"},{"creatorName":"Morita, Shuji","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00002498896.pdf","filesize":[{"value":"652.4 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00002498896.pdf","url":"https://kpu.repo.nii.ac.jp/record/4953/files/KJ00002498896.pdf"},"version_id":"3f7132c7-7ece-4bd8-b25f-f970b61f0e4e"}]},"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":"departmental bulletin paper"}]},"item_title":"ゲル滬過法によるフルボ酸の分画とそのキレート能について(農芸化学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ゲル滬過法によるフルボ酸の分画とそのキレート能について(農芸化学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["419"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4953","relation_version_is_last":true,"title":["ゲル滬過法によるフルボ酸の分画とそのキレート能について(農芸化学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-26T05:06:57.276123+00:00"}
