Electrokinetic determination of the buffer capacity of Andisols.

Among methods which involve the flow of electric current, the electro-remediation techniques have shown useful both for the removal of polluting species, and for obtaining a series of parameters in relatively laboratory simple experiments which can be used to characterize soils. This technique was applied in the present study to obtain experimental results with two soils from Tenerife. The capacity of the method as methodology for the measurement of the buffering capacity of these soils during electrokinetic experiments was analyzed.
