This complex is soluble in CHCl<SUB>3</SUB> but insoluble in water. It was observed that the maximum complex formation and extraction were performed below pH 4.5. The CHCl<SUB>3</SUB> extract showed the absorption peak at 390 nm. The maximum color development in CHCl<SUB>3</SUB> phase was obtained by the use of 1.5 to 7.0 mM (I)-CHCl<SUB>3</SUB> solution. The extraction needs more than 3 minutes. From these results the procedure was established as follows; To sample solution containing 0 to 60μg of Mo(VI) add 6 ml of acetate-HCl buffer solution and adjust the pH to 1.0. Dilute the solution to 25 ml with distilled water and transfer into a separatory funnel. Add 10 ml of 2.5 mM (I)-CHCl<SUB>3</SUB> solution and shake for 5 minutes. Separate the CHCl<SUB>3</SUB> phase and measure the absorbance at 392 nm (more suitable than 390 nm) against a reagent blank. The calibration curve was linear in the range of 0 to 6.0 ppm Mo(VI) in a CHCl<SUB>3</SUB> solution and the apparent molar absorptivity was 1.09×10<SUP>4</SUP>. The effect of 23 ions was studied and it was found that the tolerable amount of these ions was considerably high except Fe(III), Sn(II), Cu(II), V(V) and W(VI)."},{"@value":"5-クロロ-7-ヨード-8-キノリノールによるモリブデン(VI)の吸光光度定量法について検討した.モリブデン(VI)は,pH1.0では5-クロロ-7-ヨード-8-キノリノールと1:2の組成の錯体をつくり,この錯体のクロロホルム中への抽出率は,水相のpHが4.5以下で実験上一定であった.錯体のクロロホルム抽出液は390nmに極大吸収を示し,検量線(ブランクの吸収を考慮して392nmで作成)はモリブデン(VI)が0～6.0ppmの範囲で直線となり,この波長における錯体の見掛けのモル吸光係数は1.09×10<SUP>4</SUP>であった.23種の共存イオンの影響を検討したが,銅(II),バナジウム(V),タングステン(VI),鉄(III)及びスズ(II)を除けば,許容量は相当高かった."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410290696493512833","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020702033"},{"@type":"NRID","@value":"9000003135635"}],"foaf:name":[{"@language":"en","@value":"OHTA Naoichi"},{"@language":"ja","@value":"太田 直一"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Faculty of Science, Tokyo Metropolitan University"},{"@language":"ja","@value":"東京都立大学理学部化学教室"}]},{"@id":"https://cir.nii.ac.jp/crid/1410290696493512832","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020702048"},{"@type":"NRID","@value":"9000004509916"}],"foaf:name":[{"@language":"en","@value":"TERAI Minoru"},{"@language":"ja","@value":"寺井 稔"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Faculty of Science, Tokyo Metropolitan University"},{"@language":"ja","@value":"東京都立大学理学部化学教室"}]},{"@id":"https://cir.nii.ac.jp/crid/1410290696493512834","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020702042"},{"@type":"NRID","@value":"9000004514635"}],"foaf:name":[{"@language":"en","@value":"MURAHASHI Syuichi"},{"@language":"ja","@value":"村橋 秀一"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Faculty of Science, Tokyo Metropolitan University"},{"@language":"ja","@value":"東京都立大学理学部化学教室"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"05251931"},{"@type":"NDL_BIB_ID","@value":"000000021279"},{"@type":"ISSN","@value":"05251931"},{"@type":"LISSN","@value":"05251931"},{"@type":"NCID","@value":"AN00222633"}],"prism:publicationName":[{"@language":"ja","@value":"分析化学"},{"@language":"en","@value":"BUNSEKI KAGAKU"},{"@language":"en","@value":"BUNSEKI KAGAKU"},{"@language":"en","@value":"Bunseki kagaku"},{"@language":"ja","@value":"分析化学"}],"dc:publisher":[{"@language":"en","@value":"The Japan Society for Analytical Chemistry"},{"@language":"ja","@value":"公益社団法人 日本分析化学会"}],"prism:publicationDate":"1976","prism:volume":"25","prism:number":"9","prism:startingPage":"573","prism:endingPage":"577"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","url":[{"@id":"http://id.ndl.go.jp/bib/1730394"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I1730394"},{"@id":"https://dl.ndl.go.jp/pid/10888114"},{"@id":"http://id.ndl.go.jp/digimeta/10888114"},{"@id":"http://www.jstage.jst.go.jp/article/bunsekikagaku1952/25/9/25_9_573/_pdf"},{"@id":"http://dl.ndl.go.jp/info:ndljp/pid/10888114"}],"availableAt":"1976","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=5-Chloro-7-iodo-8-quinolinol","dc:title":"5-Chloro-7-iodo-8-quinolinol"},{"@id":"https://cir.nii.ac.jp/all?q=Molybdenum%20(VI)","dc:title":"Molybdenum (VI)"},{"@id":"https://cir.nii.ac.jp/all?q=Solvent%20extraction","dc:title":"Solvent extraction"},{"@id":"https://cir.nii.ac.jp/all?q=Spectrophotometry","dc:title":"Spectrophotometry"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:0034296247"},{"@type":"NDL_SEARCH","@value":"oai:ndlsearch.ndl.go.jp:R000000004-I1730394"},{"@type":"NDL_SEARCH","@value":"oai:ndlsearch.ndl.go.jp:R100000039-I10888114"},{"@type":"CROSSREF","@value":"10.2116/bunsekikagaku.25.573"},{"@type":"NDL_DC","@value":"info:ndljp/pid/10888114"},{"@type":"CIA","@value":"110002910396"},{"@type":"OPENAIRE","@value":"doi_dedup___::2d88e5995f040877cc4429d235303335"}]}
