Flow injection spectrophotometric determination of bromoxynil herbicide by diazotization method.
A flow injection spectrophotometric method is proposed for the determination of bromoxynil herbicide. Bromoxynil was hydrolyzed with HCl and the resulting product, 3,5-dibromo-4-hydroxyaniline, was diazotized with nitrite and coupled with aniline. The absorbance of the azo dye was measured at 500 nm. The conditions were optimized for diazotization using FIA. The range of linearity was found to ...
متن کاملSpectrophotometric Determination of Vancomycin Hydrochloride in Pharmaceutical Preparations through Diazotization and Coupling Reactions
Two simple, sensitive, accurate and economic methods A and B have been developed for the quantitative estimation of vancomycin hydrochlorid (VHC) and its formulations using another two drug compounds as a coupling reagents.The proposed methods are based on a coupling reaction between VHC and diazotized procain (method A) or diazotized sulphacetamide sodium (method B) in alkaline medium to form ...
متن کاملTitrimetric and Spectrophotometric Determination of Tinidazole Tablets
A simple, sensitive, rapid, reproducible, economical and easily accessible method for the determination of tinidazole tablets is described. From the experiment carried out there is the need for recrystallisation of tinidazole tablet before it is analysized. Ultraviolet (UV) absorption analysis corresponds to the result obtained with non-aqueous titration. And the best solvent to be use for non-...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولSpectrophotometric Determination of Allopurinol Drug in Tablets
Spectrophotometric micro determination of allopurinol (ALP) via charge-transfer formation is described. This includes the utility of some π-acceptors such as 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and 3,6-dichloro-2,5-dihydroxy-p-benzoquinone (p-CLA) for estimation of ALP drug (act as è-donor). These reactions are applied for determination of ALP in its pharmaceutical preparations coming...
