A spectrofluorimetrical selective method was designed for determination of paracetamol in tablets. This important technique can be characterized by its sensitivity, simplicity, celerity and cheaper cost than current official methods. The employed methodology involves coumarinic compound formation obtained by reaction between paracetamol and(More)
A new spectrofluorimetric method for the enalapril maleate monitoring was studied. Enalapril maleate was found to be highly photolabile. This drug was evaluated according to photodegradation assay at pH 2.5 and 6. Enalapril maleate was exposed to UVA–UVB radiations. Under these specific conditions was found as degradation product, the diketopiperazine. The(More)
In this work a simple and sensitive fluorimetric method for determination of salbutamol (4-[2-(tert-butylamino)-1-hydroxyethyl]-2-(hydroxymethyl) phenol) using an Eu enhanced signal was developed. The employed methodology is based on the formation of a ternary complex formed with Eu, salbutamol and trioctylphosphine oxide (TOPO). Intermolecular transfer of(More)
