Spectrophotometric Determination of Drugs Using Iodine As Analytical Reagent
Six drugs viz., Astemizole, Cisapride, Domperidone, Pantoprazole, Rabeprazole and Trazadone were tested for the formation of charge transfer complexes with Iodine. Each of these drugs turned the violet coloured i.e iodine , in CH2Cl2, to brown and exhibited a new band at 366nm in addition to the original band of iodine at 510nm due to anion of the reagent whose intensity increased with increase...
متن کاملA facile spectrophotometric method for the determination of selenium.
A rapid and sensitive spectrophotometric method is described for the determination of trace amounts of selenium using Variamine Blue (VB) as a chromogenic reagent. The proposed method is based on the reaction of selenium with potassium iodide in an acidic medium to liberate iodine, which oxidizes Variamine Blue to form a violet-colored species having an absorption maximum at 546 nm. Beer's law ...
متن کاملApplication of Differential Kinetic Method Using ANN with a New Synthetic Reagent for Simultaneous Spectrophotometric Determination of Mercury and Palladium
A new selective reagent was used for simultaneous determination of mercury and palladium in real samples with their different kinetic spectrophotometric properties. The method is based on the difference in the rate of the oxidation reaction of the recently synthesized reagent, nitro benzoyl diphenylmethylen phosphorane (N-BDMP), with Hg2+ and Pd2+. The kinetic profiles were monitored and record...
متن کاملQuantitative Determination of drugs & pharnaceuticalsby using iodine as analytical reagent: A spectrophotometric study
Sensitive, accurate and precise methods for the qauantitative determination of Seven drugs viz., Cyclobenzaprine HCl (CYC), Cyproheptadine HCl (CYP), Dobutamine HCl (DOB), Moxifloxacin HCl (MOX), Pamiprioxole HCl (PAM), Sumatriptan succinate (SUM) and Trimetazadine 2HCl(TRI) haave been developed . The methods are based on the charge transfer interqction of iodine with drugs which resulted in th...
متن کاملA Facile Spectrophotometric Method for the Determination of Hypochlorite using Rhodamine B
Um método espectrofotométrico simples, rápido e sensível foi desenvolvido para a determinação de hipoclorito usando Rodamina B. O método proposto considera a reação de hipoclorito com iodeto de potássio em meio ácido, com liberação de iodo. O iodo liberado descora a solução vermelho-rosada de Rodamina B que pode ser medida em 553 nm. Este decréscimo na absorbância é diretamente proporcional à c...
