Flow Injection Spectrophotometric Determination of Fenoxaprop-p-ethyl Herbicide in Different Grain Samples after Derivatization
Propomos um método espectrofotométrico para a determinação do herbicida fenoxaprop-p-etil, usando injeção em fluxo.O fenoxaprop-p-etil foi convertido num ácido hidroxamico, na presença de hidroxilamina dihidrocloridrica em meio alcalino. O ácido hidroxâmico obtido reagiu com ferro(III) formando um complexo hidroxamato de ferro(III), vermelho. A absorbância do complexo foi medida a 500 nm em sis...
متن کاملSpectrophotometric Determination of Formaldehyde in Seawater Samples after In-situ Derivatization and Dispersive Liquid-Liquid Microextraction
In this paper, a simple dispersive liquid-liquid microextraction for the extraction and pre-concentration of formaldehyde in seawater samples followed with spectrophotometric is proposed. Formaldehyde was derivatized in situ with acetyl acetone in the presence of ammonium acetate in a single step. Then it was collected into a mixture of ethanol (disperser solvent) and chloroform (extracting...
متن کاملFlow 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 کاملFlow Injection Spectrophotometric determination of Doxorubicin Hydrochloride in Urine samples
A simple and fast FI colorimetric procedure for determination of doxorubicin hydrochloride (DXH) was proposed. It is based on the redox reaction between iron (III) and DXH, resulting in an intensely red colored complex in the presence of 1, 10-orthophenantroline which can be followed by spectrophotometric measurement at λmax= 510 nm. This is an automatic way to determine doxorubicin hydrochlori...
متن کاملFlow injection spectrophotometric determination of amoxicillin in pharmaceutical samples by coupling with diazotized p- nitroaniline
A spectrophotometric method using flow injection analysis (FIA) is described for the determination of amoxicillin (AMX). Its detection limit, linearity and reproducibility were examined.The automated method is based on a coupling reaction between AMX and diazotized paranitroaniline (DPNA) in alkaline medium to form an intense reddishorange, water-soluble dye that is stable and has a maximum abs...
