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
