A. Hamza scite author profile

Based on the redox characteristics of two selected organochlorine pesticides namely alachlor (ALC) and chlorfenvinphos (CHL) in Britton-Robinson (B-R) buffer at a hanging mercury drop, Pt and Au working electrode (HMDE), a fast, simple and selective differential pulse cathodic stripping voltammetric (DP CSV) method was developed for their determination. The cathodic stripping peak currents for ALC versus concentrations was linear in the range from 7.4 10 À9 to 1.4 10 À7 mol L À1 and in the range from 2.7 10 À9 to 1.6 10 À8 mol L À1 for CHL. The method was applied for the analysis of trace concentrations of ALC and CHL in fresh-and marine water (Atlantic and Red Sea) and sediment samples and food stuffs.
