A promising Electrochemical Test for Evaluating the Hydrocarbon – Type Pollutants Contained in Industrial Waste Soils

Soil pollution has become one of the most serious problems due to its negative repercussion on ecosystems. For this reason, different analytical techniques have been developed to evaluate the quantity of organic pollutants using electrochemical techniques that are based on the polarity of solvents, and by verifying the change in the resistance of ionic transference originating from the pollutants in the form of hydrocarbons present in soil with the use of electrochemical impedance spectroscopy.The good response of the electrochemical impedance spectroscopy test for evaluating hydrocarbon – type pollutants contained in industrial waste soils was verified across the interaction hydrocarbon – soil, where the clean soil showed increased ionic transference in a logarithmic manner with increasing particle size; in contrast, polluted soil showed decreased ionic transference in an exponential manner with increasing particle size. These results were verified with Soxhlet extraction and quantification of hydrocarbon in polluted soil.
