Electrokinetic determination of the buffer capacity of Andisols (original) (raw)

Science of The Total Environment, 2007

Abstract

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. The results obtained on electrokinetic determination of buffer capacity correlated quite well with behaviour observed in the pH curves. The technique was promising for soil description primarily because important information could be obtained in shorter time periods than those required when using routine laboratory methods of soil analysis.
