The purpose of this investigation was to evaluate the soil ability to sorb added soluble fluoride, through a short experiment – 1 hour to 10 days. All analyzed soil samples contain high total fluoride (over 300 ppm) from geochemical sources, but there is also an evidence of soil contamination with fluoride from sewage materials from the aluminum plant. Both soil types have shown significant ability to adsorb added soluble F, although acid cambisol had more favorable conditions for the fluoride adsorption. The results obtained indicate that, in the case of soils contamination with fluoride, its higher accumulation in plants could be expected in fluvisols.

Key words: fluoride, sorption, aluminum, soil, pH, contamination

Zadržavanje dodatog fluora u dva različita zemljišta  iz crne gore

Svrha ovog istraživanja je da procijeni sposobnost zemljišta da adsorbuje dodati rastvorljivi fluorid, preko kratkog eksperimenta od 1 sata do 10 dana. Svi analizirani uzorci zemljišta sadrže visok procenat fluora (preko 300 ppm) iz geohemijskih izvora, ali takodje postoji dokaz o zagadjenju zemlje fluorom od otpadnog materijala iz fabrike aluminijuma. Oba tipa zemljišta su pokazala značajnu sposobnost  da adsorbuju dodati rastvorljivi F, mada kiseli cambisol ima pogodnije uslove za adsorbciju fluora. Dobijeni rezultati ukazuju na to da, u slučaju zagadjenja zemljišta fluorom, može se očekivati njegova veća akumulacija u biljkama na fluvisolu.
