Voltammetric determination of salbutamol, sulfamethoxazole, and trimethoprim as anthropogenic impact indicators using commercial screen-printed electrodes

A voltammetric method based on the use of screen-printed carbon electrodes (SPCEs) is presented for the simultaneous determination of salbutamol (SAL), sulfamethoxazole (SMX), and trimethoprim (TMP), with high sensitivity, fast response, and excellent repeatability and reproducibility. Under the opt...
