The electrochemical behavior of valproic acid (VAL) was investigated using square wave voltammetry, cyclic voltammetry, and sampled direct current polarography and a new square wave voltammetric method was developed for determination of VAL in pharmaceutical preparations. Recovery studies for the accuracy of the method were performed by adding known amounts of VAL and it was found to be 109.67 ± 4.85%. The proposed method was successfully applied to pharmaceutical products on the market. |
