Spectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some Fluoroquinolones
Simple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first meth...
متن کاملSpectrophotometric Determination of Some Fluoroquinolones
Two simple, rapid and sensitive spectrophotometric methods for the determination of three fluoroquinolones, namely levofloxacin, norfloxacin and ciprofloxacin have been performed either in pure form or in their tablets. In the first method, levofloxacin and norfloxacin are directly treated with bromocresol green (BCG) in dichloromethane while ciprofloxacin is allowed to react with the same dye ...
متن کاملAtomic Absorption Spectrometric Determination of Lead after Extraction and Preconcentration with 5-Br-PADAP
Lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the pH range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. After filtration, the solid mass consisting of the lead complex and naphthalene was dissolved wi...
متن کاملExtraction separation and electrothermal atomic absorption spectrometric determination of thallium in some sulfide minerals.
A method for thallium determination in some sulfide minerals (sphalerite, galena, orpiment and realgar) by electrothermal atomic absorption spectrometry has been proposed. Mineral samples were dissolved in a mixture of HNO3 and HCl. The effect of interfering elements (Zn, Pb and As) on the determination of Tl in the investigated minerals was studied. These investigations show that it is not pos...
متن کاملAtomic absorption spectrometric determination of selenium in human blood components.
We separated blood from five healthy blood donors into plasma, erythrocytes, platelets, and leukocytes; counted the number of cells in each fraction; and determined the selenium content of each component by hydride generation atomic absorption spectrometry. The mean (+/- SD) selenium concentrations and amounts measured were as follows: whole blood 102.3 +/- 16.1 micrograms/L, plasma 76.9 +/- 10...
