DEP-On-Go for Simultaneous Sensing of Multiple Heavy Metals Pollutants in Environmental Samples.

ABSTRACT: We describe a simple and affordable "Disposable electrode printed (DEP)-On-Go" sensing platform for the rapid on-site monitoring of trace heavy metal pollutants in environmental samples for early warning by developing a mobile electrochemical device composed of palm-sized potentiostat and disposable unmodified screen-printed electrode chips. We present the analytical performance of our device for the sensitive detection of major heavy metal ions, namely, mercury, cadmium, lead, arsenic, zinc, and copper with detection limits of 1.5, 2.6, 4.0, 5.0, 14.4, and, 15.5 μg·L-1, respectively. Importantly, the utility of this device is extended to detect multiple heavy metals simultaneously with well-defined voltammograms and similar sensitivity. Finally, "DEP-On-Go" was successfully applied to det
