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 کاملThiocyanate determination by ion pair chromatography
Department of Analytical and Environmental Chemistry, Vilnius University, Naugarduko 24, LT-03225 Vilnius, Lithuania A simple and rapid ion pair chromatographic method has been developed for the determination of thiocyanate. Separation was carried out on a 25 cm × 4.6 mm Ascentis C18 column (5 μm particle size) with a mobile phase containing 2 mmol/l tetrabutylammonium (TBA)-phosphate (pH 6.5) ...
متن کاملExtractive liquid-liquid spectrophotometric procedure for the determination of thiocyanate ions employing the ion pair reagent amiloride monohydrochloride.
An accurate, inexpensive and less laborious liquid-liquid extractive spectrophotometric procedure for the determination of thiocyanate ions in aqueous media has been developed. The method has been based upon the formation of a yellow colored complex ion associate of the ion-pairing reagent 1-(3, 5-diamino-6-chloropyrazinecarboxyl) guanidine hydrochloride monohydrate, namely amiloride hydrochlor...
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...
متن کاملEXTRACTIVE-SPECTROPHOTOMETRIC DETERMINATION OF VANADIUM(V) AS AN ION-ASSOCIATION COMPLEX WITH 4-(2-PYRIDYLAZ0)-RESORCINOALN D TETRABUTYLAMMONIUM PERCHLORATE
A simple and sensitive extractive- spectrophotometric method for thedeterrnination of trace amounts of vanadium(V) is reported. The method is based on the quantitative extraction of the anion complex of V(V) with 4-(2-pyridy1azo)-resorcinol with tetrabutylammonium perchlorate into chloroform, followed by spectrophotometric measurements at 554 nm. Beer's law is obeyed over the concentration ...
