The rate of the photo-sensitized reaction was of half-order regarding both the light intensity irradiated and the concentrations of iodine, which correspond to those of the triiodide ion in the presence of excess iodide ions, and was proportional to the concentration of the diamine-N-polycarboxylate ion. Further, the rate was of half-order for concentrations of I− below 3×10−4 mol dm−3 and was of inversely half-order for concentrations of I− above 6×10−4 mol dm−3. The reaction was inhibited by radical scavengers of acrylonitrile, acrylamide, and hexaamminecobalt(III) ions. Both hydrogen ion and complex forming metal ions, such as copper(II) and zinc(II), are also strong inhibitors of the reaction. The reaction mechanism, where initiation reaction is a photo-dissociation of iodine and the reactive species is a I2\\divdot radical anion, is proposed to account for the obtained results.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1030003658312625792","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"90007138"},{"@type":"NRID","@value":"1000090007138"},{"@type":"NRID","@value":"9000258665973"},{"@type":"NRID","@value":"9000002562050"},{"@type":"NRID","@value":"9000253104525"},{"@type":"NRID","@value":"9000256018513"},{"@type":"NRID","@value":"9000021901386"},{"@type":"NRID","@value":"9000256012464"},{"@type":"NRID","@value":"9000256009365"},{"@type":"NRID","@value":"9000018353727"},{"@type":"NRID","@value":"9000256010934"},{"@type":"NRID","@value":"9000256014874"},{"@type":"NRID","@value":"9000021841003"},{"@type":"NRID","@value":"9000256012644"},{"@type":"NRID","@value":"9000256017658"},{"@type":"NRID","@value":"9000256008571"},{"@type":"NRID","@value":"9000255706499"},{"@type":"NRID","@value":"9000000797462"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0015352"}],"foaf:name":[{"@value":"Masaru Kimura"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Nara Women’s University"}]},{"@id":"https://cir.nii.ac.jp/crid/1582543027630420610","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021841007"}],"foaf:name":[{"@value":"Akiko Ohomura"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Nara Women’s University"}]},{"@id":"https://cir.nii.ac.jp/crid/1582543027630420609","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021841011"},{"@type":"NRID","@value":"9000256008572"}],"foaf:name":[{"@value":"Fumiko Nakazawa"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Nara Women’s University"}]},{"@id":"https://cir.nii.ac.jp/crid/1582543027630420608","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021841015"},{"@type":"NRID","@value":"9000256008573"}],"foaf:name":[{"@value":"Keiichi Tsukahara"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry, Faculty of Science, Nara Women’s University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00092673"},{"@type":"EISSN","@value":"13480634"}],"prism:publicationName":[{"@value":"Bulletin of the Chemical Society of Japan"}],"dc:publisher":[{"@value":"Oxford University Press (OUP)"}],"prism:publicationDate":"1991-06-01","prism:volume":"64","prism:number":"6","prism:startingPage":"1872","prism:endingPage":"1877"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://academic.oup.com/pages/standard-publication-reuse-rights"],"url":[{"@id":"https://academic.oup.com/bcsj/article-pdf/64/6/1872/56185959/bcsj.64.1872.pdf"},{"@id":"https://academic.oup.com/bcsj/article-pdf/65/7/1812/56221972/bcsj.65.1812.pdf"}],"createdAt":"2006-07-26","modifiedAt":"2024-01-19","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=General%20Chemistry","dc:title":"General Chemistry"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360283694080619264","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Kinetic Studies of the Reaction of Nitrous Acid with Iodide Ion in the Presence of Molecular Oxygen in an Acid Solution"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283694081277056","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Kinetics and Mechanism of the Oxidation of [Fe(CN)6]4− to [Fe(CN)6]3−, Induced by the Reaction between Cu2+ and I− in Aqueous Solution.
