The ZNPs film was highly stable and could selectively adsorb molecules containing phosphoric groups. Therefore, a sensor was developed for the determination of parathion based on the ZNPs electrodeposited on the SAM modified gold electrode. The electrochemistry of parathion on the present electrode was studied using cyclic voltammetry and square-wave voltammetry. A linear adsorptive stripping voltammetric response over the concentration range from 0.005 to 1.0μg ml−1 (after a 2-min adsorption) was obtained under the optimized operational parameters of square wave voltammetry. The limit of detection was 0.8ng ml−1 (S/N = 3). The ZNPs modified on SAM surface of gold electrode exhibits acceptable reproducibility (RSD 4.16%, n = 10) and a good stability. The electrode was applied to the determination of parathion in real samples, and satisfactory results were obtained.
