Abstract
Voltammetric and amperometric detection of paraquat (PQ) herbicide from aqueous solutions has been successfully achieved using a boron-doped diamond (BDD) electrode modified with platinum particles. Electrochemical deposition of platinum was performed by chronoamperometry technique operated at two potential levels, i.e., -0.15 V for 1 s and 0.1 V for 6s. Operational parameters of electrochemical techniques tested in detection application were determined in order to achieve superior electroanalytical performances for quantitative assessment of paraquat concentration at trace level. Both cyclic voltammetry and multiple-pulsed amperometry exhibited best electroanalytical performances in terms of sensitivity and lowest detection limit, in comparison with the other applied voltammetric pulsed techniques.
