Considering the severe threat of arsenic contamination in drinking water on the life of millions of people around the world‐different technologies and materials have been employed throughout the ages to provide arsenic‐free drinking water. This work, demonstrates a facile fabrication of a low‐cost, bio‐friendly p‐type functionalized multiwalled carbon nanotubes (f‐MWCNTs)/n‐type anodized stainless steel (SS) hybrid material, which is used as an effective electrode for the easy and fast oxidation of arsenic(III) to arsenic(V), by applying relatively low positive voltage, to subsequently increase the proficiency of the process. This new material based technology used in this work is found very effective in oxidizing comparatively lower concentrations of arsenic (III) (<100 ppb) present in drinking water at 30 °C at a pH suitable for drinking water (6.5‐8.5). Fabrication of such interfacial band engineered nano‐hybrid electrode is beneficial to enhance the anodic current, which in turn, increases the As(III) oxidation. Based on the design of the electrode, the hole mediated anodic current is found to boost the oxidization of As(III). This technology could reduce the use of ultraviolet radiation and other use of costly oxidants for the oxidation of As(III) and thus can appear as a cost‐effective, energy‐efficient technique for the oxidizing of As(III) from drinking water.
