Chemical reactions, electrokinetic control

Fletcher, P. D. L, Haswell, S. J., Zhang, X., Electrokinetic control of a chemical reaction in a lab-on-a-chip micro-... 

The electric current generates at the electrodes several products that can dramatically affect the electrokinetic treatment. The effect of water electrolysis is well known, but any type of enhancements by the addition of other chemicals should consider its potential for the generation of harmful/hazardous by-products. Byproducts can also be formed by certain undesirable reactions of the metal species with naturally occurring ions. Therefore, the selection of any chemical for pH control or for heavy metal complexing must consider the possible reactions upon the electrodes and into the soil with the pollutant or other components of the soil.
