Square-wave Voltammetric Determination of Propyphenazone, Paracetamol, and Caffeine: Comparative Study between Batch Injection Analysis and Conventional Electrochemical Systems

Autor: Raquel M. F. Sousa, Luiz A. J. Silva, Clarice H. França, Rodrigo A.A. Munoz, Eduardo M. Richter, Weberson P. Silva

Publikováno v: Electroanalysis. 29:1860-1866

In this work, the performance of two methods for simultaneous determination of propyphenazone (PRO), paracetamol (PAR), and caffeine (CAF) were compared. One is based on the use of a conventional electrochemical cell (steady-state condition) and the

Investigation of midazolam electro-oxidation on boron doped diamond electrode by voltammetric techniques and density functional theory calculations: Application in beverage samples

Autor: Eduardo M. Richter, Raquel M. F. Sousa, Mário H. P. Santana, Raquel G. Rocha, Weberson P. Silva, Moacyr Comar Júnior, Rodrigo A.A. Munoz

Publikováno v: Talanta. 207

Midazolam (MID) is a sedative drug which can be added in beverage samples as drug-facilitated-sexual assault (date rape drug). This type of drug has short half-life in biological fluids (not detectable) which often prevents the correlation between dr

A simple and fast batch injection analysis method for simultaneous determination of phenazopyridine, sulfamethoxazole, and trimethoprim on boron-doped diamond electrode

Autor: Weberson P. Silva, Rodrigo A.A. Munoz, Polyana Fernandes Pereira, Eduardo M. Richter

Publikováno v: Journal of Electroanalytical Chemistry. 766:87-93

A new analytical procedure for fast and simultaneous determination of sulfamethoxazole (SMX), trimethoprim (TMP) and phenazopyridine (FZP) has been developed. The method is based on batch injection analysis with multiple pulse amperometric detection
