CERVIGNANO SOIL
YEAR 2013 – Part two
Study of the behaviour of Chromium in soils
- added as pure salt of Cr(III) or Cr(VI)
- when coming from industrial sludges used
as fertilizers i.e. compost from tanneries – Cr(III)
Different oxidation states/different behaviour in soil
Cr(III) is a cation Cr3+
Cr(VI) is an anion CrO42-
Microcosmos experimental trials - CHROMIUM
Experimental part - Summer stage
Thesis 1 - Cr(NO3)3 added
1600 mg/Kg of Cr(III)
Thesis 2 - Tannery sludge
added
1600 mg/Kg of Cr(III)
Thesis 3 - K2CrO4 added
500 mg/Kg of Cr(VI)
+ Control (blanck)
Six elutions with 350 mL
water (50 mm of rain)
from 06/06/2013
to 11/07/2013

In 2013 we just experimented materials and methods
YEAR 2014 We started with a new set of experiments
Study of the behaviour of Chromium in soils - added as pure salt - when coming from industrial sludges used as fertilizers (compost coming from tanneries) - in different situations more organic substrate more bacteria activity
Conclusions
New experimental plan
Thesis 1 - Cr(NO3)3 added
1600 mg/Kg of Cr(III)
Thesis 2 - Tannery sludge
added
1600 mg/Kg of Cr(III)
Thesis 3 - K2CrO4 added
150 mg/Kg of Cr(VI)
Thesis 4 - K2CrO4 added
