Abstract
In the study was developed a new method for the treatment
soils contaminated by polychlorinated dibenzodioxin and
dibenzofuran. The method is based on attrition of soil so
that the contaminants absorbed on the particle surfaces
are liberated with the fine fraction formed in the
attrition process. Same the attrition process produces
active surface which can absorb the free contaminants.
Before starting the remediation process must be decided
the limit value under which the residual concentration
must lie. Then in the laboratory is performed an
experiment in the base of which is determined the grain
size level; material under which much be removed together
with the contaminant. In the real sample has been found
that after the attrition the limit value 0.5 ng/g (I-TEQ)
is obtained when the fine under 0.1mm fraction (20% of
the original soils amount) is removed together with the
contaminants 96% (original level 10 ng/g; 100%). (7
