Two simple and rapid spectrophotometric methods were developed for the determination of two binary mixtures: moxifloxacin hydrochloride (MFH) with ketorolac tromethamine (KTM) and ciprofloxacin hydrochloride (CFH) with dexamethasone sodium phosphate (DSP). The first method, zero-crossing derivative spectrophotometry, depends on measuring the second derivative peak and trough values at 304 nm an...

in this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (cpe-scanometry) as a new, facile, available, fast, sensitive, and low cost method. the method is based on the cpe of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to plexiglas®cell and scanning the cells containing the analyte so...

two rapid, simple, sensitive and cost-effective titrimetric and spectr-ophotometric methods are described for the determination of albendazole (alb) in bulk drug and in pharmaceuticals. in titrimetry (method a), alb is oxidized by a known excess of potassium permanganate (kmno 4 ) in h 2 so 4 medium followed by the determination of unreacted permanganate by titration with ferrous ammonium sulph...
