BARROS GOMES, Paulo Roberto et al. Use of automatic methods in fluxes with spectrophotometric detection in the determination of diclofenac sodium in pharmaceutical formulations and body fluids. Rev. colomb. cienc. quim. farm. [online]. 2019, vol.48, n.1, pp.29-43. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v48n1.80063.

This study described and compared four studies that used automatic flow methods with spectrophotometric detection and the oxidation reaction of diclofenac to determine diclofenac in pharmaceutical formulations and body fluids. For this, the following articles were used: Versatility of a multicommuted flow system in the spectrometric determination of three analytes, Sequential injection spectrophotometric method for the assay of anti-inflammatory diclofenac sodium in pharmaceutical preparations, Screening of conditions controlling spectrophotometric sequential injection analysis and Sequential injection spectrophotometric determination of diclofenac in urine and pharmaceutical formulations and we detail the methodologies used, the results, the conclusions obtained and compare the limits of detection, relative standard deviation and analytical frequency. The results showed significant differences between the employed methods and the use of the Automatic System of the Sequential Injection Analysis type, although this one has a lower analytical frequency.

Palavras-chave : FIA-Multicomutation; sequential injection analysis; spectrophotometry; sodium diclofenac; oxidation.
