Abstract: Acetylene black modified carbon paste electrode is prepared.Electrochemical behaviors of mercury ion on the bare carbon paste electrode and the prepared acetylene black modified carbon paste electrode are investigated by the cyclic voltammetry.It is found from experimental results that mercury ion has an obvious redox peak on the acetylene black modified carbon paste electrode.The detection conditions are optimized at the same time.Under the optimized conditions,the oxidation peak currents are proportional to mercury ion concentration in the range of 3.0×10-7-2.4×10-5 mol·L-1,with a detection limit of 2.3×10-8 mol·L-1.The trace amounts of mercury ion in simulated water samples are successfully detected through standard addition method.
