Abstract AR
تم تطوير طريقتان طيفيتان تميزتا بالبساطة والحساسية في تقدير 1 – نفثول.
اعتمدت الطريقتان (A و B) على تفاعل 1-نفثول بوصفه مانحا للإلكترونات نوع n مع كل من الكلورانيل و 2, 3–ثنائي كلورو–5, 6 – ثنائي سيانو–1, 4–بارابنزوكوينون بوصفهما مستقبلات للإلكترونات نوع π لإعطاء معقدات ملونة في المحلول المائي تمتلك أقصى امتصاص عند الأطوال الموجية 349 و 423 نانوميتر على التوالي .أمكن تطبيق قانون بير للتراكيز 1 – 36 و 0.4 – 5 مايكروغرام /مللتر و بامتصاصيات مولارية 2.59 × 103 و 94.9 × 103 لتر.مول -1 سم-1 للطريقتين A و B على التوالي.
Abstract EN
Two new simple, sensitive and economical spectrophotometric methods have been developed for the determination of 1-naphthol in pure form.
These methods are based on the reaction of 1-naphthol as n-electron donor with chloranil in method A and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in method B as π-acceptors to give highly coloured complex species in aqueous solution which are absorb maximally at 349nm and 423 nm respectively.
Beer's law is obeyed in the concentration ranges 1-36 μg ml-1 and 0.4-5.0 μg ml-1 with high apparent molar absorptivities of 2.59 × 103and 94.9 × 103 for methods A and B respectively.
