Spectrophotometric determination of a few commercial drugs using NBS and Rhodamine-B Couple
Simple, sensitive and selective methods are developed for the spectrophotometric determination of drugs, viz., Montelukast sodium, Prasugrel, Ondensetron, Rosuvastatin calcium, Amlodepine besylate based on their reactivity towards Nbromosuccinimide (NBS). The method involves the addition of excess NBS of known concentration in the presence of 1M HCl, reactants are allowed to react and the unrea...
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...
متن کاملDetermination of thallium(I) by flotation-spectrophotometric method using iodide and rhodamine B.
A method for the trace amount determination of Tl(I), via its preconcentration, is proposed. The method is based on the reaction of iodide, Tl(I) and Rhodamine B in a weakly acidic medium. In this process an ion-associated complex is formed, which is floated at the interface of aqueous-cyclohexane layers. Various amounts of Tl(I) by a subsequent separation and dissolution of the floated complex...
متن کاملFlotation Spectrophotometric Determination Of Platinum With Isochromatic Ion-Pair Between Tetrabromofluorescein And Rhodamine 6G
The flotation spectrophotometric method for determination of platinum (Pt) with isochromatic dye ion-pair was described. [(2R6G) (PtBr6)⋅3(R6G⋅Br)] was resolved and Rhodamine 6G (R6G) was entered into aqueous phase when pH = 5.5 HAc-NaAc buffer solution was added to the [(2R6G) (PtBr6)⋅3(R6G⋅Br)] in medium of toluene. And then R6G·TBF was flotated by tetrabromofluorescein (TBF) with toluene. Th...
