New Spectrophotometric Estimation and Cloud Point Extraction of Cefdinir
Baghdad Science Journal, 2018 A sensitive spectrophotometric method was developed for the estimation of cefdinir (CFD), a cephalosporin species. This study involves two methods, and the first method includes the preparing of azo dye by the reaction of CFD diazonium salt with 4-Tert-Butylphenol (4-TBP) and 2-Naphthol (2-NPT) in alkaline medium, which shows colored dyes measured at ...

Cloud point extraction for speciation of iron in beer samples by spectrophotometry
Food Chemistry, 2012 Abstract A new method based on the cloud point extraction (CPE) separation and spectrophotometric detection was proposed for the determination of iron species. In this method, Fe(II) reacts with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) in the presence of EDTA yielding a hydrophobic complex, which then is extracted into surfactant ...
