【 摘 要 】

Voltammetry using mercury electrode as working electrode has been employed in the determination of organic and inorganic compounds in several samples. A review on the applications of this analytical tool is present, covering the period of the last ten years. The emphasis of this work is directed to the hanging mercury drop electrode (HMDE), its advantages, disadvantages and applications. Voltammetric measurements are easily carried out, and present low cost. The review discusses that the use of mercury in the measurements can be a limitation due the toxicity of the element. However, nowadays the necessary of volume of Hg in the measurements is very small, and it can be reused. Thus, the correct disposal of the small amount of waste generated can be minimize environmental risks and human health, according to the principles of Green Chemistry.
