A glassy carbon electrode modified with ruthenium hexacyanoferrate (RuOHCF) was investigated as an electrocatalyst for the detection of procaine with the aim of quantification in pharmaceutical and forensic samples. The RuOHCF films were prepared by electrochemical deposition, and the parameters used in this process (concentration of RuCl 3 , K 3 Fe(CN) 6 , temperature, and number of cyclic voltammograms recorded in the modification step) were carefully optimized. Based on the optimal
more » ... achieved, the RuOHCF modified electrode allows the determination of procaine at 0.0 V with a detection limit of 11 nmol L −1 using square wave voltammetry.
