Mercury is one of the most hazardous heavy metals to human health and is hard to remove from the environmental system due to its extended half-life time and lack of decomposition. Thus, it is highly required to analyze the quantitative description of mercury in aqueous solutions through a simple, fast, and sensitive technique. In the present study, amperometric technique based on the emulsion droplet reactor (EDR) method was performed to observe the electrochemical detection of mercury ions in low concentrations. Here, the emulsion droplets were used as an extractor and reactor for mercury ions. As a result, we could measure stochastic collision events as current spikes at a cathodic potential after the contact between the emulsion droplets and electrode. In comparison with other methods, this technique permits rapid and sensitive analysis without further modification of electrode surface.
