Voltammetry for Onsite Simultaneous Metal Analysis

Heavy metals (HMs) have caused several problems for all living things on earth so far [1]. They do have both beneficial and harmful effects. Some of them in specific concentrations, oxidation numbers and forms are essential to the body of living things whereas others can be deleterious. HMs have been well known for a long time to play important roles in a number of samples especially environment and food. The greater role they have in everyday life, the greater the need for monitoring their concentrations. Several techniques have been developed to gain better figure of merits and advantages. And it would be rewarding if those techniques are able to analyze HMs simultaneously and onsite, especially for environmental analysis.
