Abstract:

The mediator-based electrochemical method is a sensitive and reliable one toward water total toxicity. The in-situ cultivated microorganism can be used as the test organisms, which endows the method high sensitivity to the changes in the total toxicity of the target water, thus enabling the method suitable for the evolution of the exact level of complex pollution of water and the design of early warning system of water quality. Here, the advance of the mediator-based electrochemical method toward water total toxicity is reviewed in term of mechanism of toxicity determination, the use of mediator and microorganism, and so on. Finally, a future perspective of the method is presented.

Key words: mediator, electrochemistry, water total toxicity, complex pollution, early warning of water quality
