Method for evaluating a pollution characteristic of a soil sample

摘要

A device for evaluating at least one pollution characteristic of natural soils contaminated by hydrocarbon compounds, said device comprising a first heater heating said sample in a non-oxidizing atmosphere, a measuring device determining an amount of hydrocarbon compounds released after feeding the sample into said first heater, a sample transfer device transferring the sample from the first heater into a second heater operating in an oxidizing atmosphere, a CO2 measuring device determining CO2 contained each effluent discharged from the two heaters, said CO2 measuring device measuring continuously the CO2 throughout the heating cycle of the first and the second heaters and including a device measuring CO contained in each effluent discharged from the two heaters, a temperature controller controlling the temperature of samples waiting to be fed into said heating means, and a device determining the pollution characteristic.
