Abstract
Arsenic (As) is a highly toxic contamination element which is especially found in drinking water [1]. Arsenic exposure to drinking water is a major concern due to environmental pollution and health hazards [2,3]. Arsenic detection in drinking water is analyzed by fabrication of an efficient electrode for demonstrating an electrochemical sensor. The electrode is based on a modified surface of the ZnO nanorods (NRs) synthesized on Ni-foam substrate by depositing α-Fe₂O₃ nanoparticles (NPs) to detect the contamination of arsenic(V) in drinking water. This electrode is synthesized through two separate growth steps which are the hydrothermal (ZnO NRs) step followed by the dip coating method (α-Fe₂O₃ NPs)...
