Abstract
Diclofenac,dissolved in a base solution of chlorhydric acid,showed a sensitive oxidation peak at 0.91 V(vs.SCE) when the solution was cyclically swept from +0.6 to +1 2 V(vs.SCE) by differential pulse voltammetry at GCE.There was a good linear relationship between the differential pulse peak current and the concentraion of diclofenac in the range from 5.0×10 -7 to 6.0×10 -6 mol/L,and the relative standard deviation is 3.5%(n=10).When determining the content of diclofenac in voltalin tablets, we have got the same results by this method as ultraviolet spectrophotometry.
