The composition of graphene oxide (GO):paraffin:nanobentonite electrode was optimized to acquire the optimal working electrode toanalyze nicotinic acid under the optimum conditions through cyclic voltammetry. Graphene oxide was synthesized from graphite byemploying the improved Hummer method. Bentonite was synthesized using the sonothermal method. The ratio of GO:paraffin:nanobentoniteelectrodes of 3:3:4 provided the optimal voltammogram. The results indicated that the composition of the comparative working electrodesof GO-modified nanobentonite was best 3:3:4 with a good peak recovery averaged value of 96.16%.
