Electrochemical detection of tellurium is interfered with arsenic due to their similar redox potentials. Gold electrodes modified by benzenedithiols (BDT) self‐assembled monolayers (SAMs) were explored to determine Te(IV) in the presence of extra As(III) in this work. SAMs of benzenedithiols on the gold surface allows for selective extraction of Te (IV) over As(III), while blocking the redox of As(III). It provides potential applications to tellurium toxicity analysis, biological membrane study and identification of geochemistry samples.
