Extractive Spectrophotometric Determination of some Drugs Through Ion-Pair Complex Formation with Thiocyanate wnd Cobalt (II) or Molybdenum (V)
Two rapid, simple and sensitive extractive specrophotometric methods has been developed for the assay of Hyoscine butyle bromide (HBB), losartan potassium (LSR) and Sertaline HCl (SER) in bulk and in their pharmaceutical formulations. The proposed methods depend upon the reaction of cobalt(II)–thiocyanate (method A) and molybdenum(V)–thiocyanate ions (method B) with the cited drugs to form stab...
متن کاملDetermination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles
Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...
متن کاملSpectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

متن کاملExtractive Spectrophotometric Determination of Nisoldipine by Ion-pair Complex Formation
Nisoldipine, a 1-4-dihydropyridine drug is determined by the development of simple and sensitive Extractive Spectrophotometric method. In the present study an ion-pair complex of amino derivative of the Nisoldipine with Bromocresol Green Solution in acidic medium is formed with subsequent extraction of the ion-pair complex in Chloroform. Maximum absorption was seen at the wavelength of 418 nm t...
