Direct, derivative spectrophotometric determination of micro amounts of Vanadium (V) by 5-bromo salicylaldehyde isonicotinoyl hydrazone
A simple and highly selective spectrophotometric method has been developed for the determination of trace amounts of V (V) using newly synthesized reagent 5-bromo salicylaldehyde isonicotinoyl hydrazone (5BrSAINH) in aqueous DMF medium. Vanadium (V) forms a brown colored soluble complex with 5-BrSAINH in the pH range 1.0-5.0. The complex shows maximum absorbance at 400nm in the pH range 4.5-5.5...
متن کاملExtractive spectrophotometric determination of ambrisentan.
PURPOSE Ambrisentan (ABS) is an antihypertensive drug used in the treatment of pulmonary atrial hypertension. The survey of literature for ABS revealed only two spectrophotometric methods for its quantification. The reported methods lack the sensitivity. This study is aimed at developing two sensitive extractive spectrophotometric methods for the determination of ABS in bulk and in tablets. M...

Four simple and sensitive extractive spectrophotometric methods have been described for the assay of Mirtazapine either in pure form or in pharmaceutical formulations. The developed methods involve formation of coloured chloroform extractable ion-pair complexes of the drug with bromocresol green (BCG), bromophenol blue (BPB), bromothymol blue (BTB) and bromocresol purple (BCP) in acidic medium....
متن کاملresponse articles: micro and macro analysis
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
