We report a sensitive electrochemical voltammetric method for analyzing p- Aminophenol, using a Natural phosphate (NP) modified carbon paste electrode NP-CPE, in Na2SO4, solution. Operational parameters have been optimized, and the stripping voltammetric performance has been studied using square wave voltammetry. The use of Moringa oleifera as natural chelating agent gave a significant improvement in the depollution of contaminated water sample.
