Influence of organic acids on heavy metals mobilization in the soil suspension

Popis výsledku v původním jazyce

Our research was aimed to demonstrate the efficiency of organic acids on the induced heavy metal mobilisation [1, 2]. Three organic acids were tested on the mobility of lead, zinc and cadmium in soil suspension of cambisol under the cultivation soil andmeadow. Acetic, tartaric and citric acids were used in concentration 5, 25 and 250 mmol.kg-1 soil. Their influence on heavy metals concentration in solution, changes of soil fraction binding and pH changes were determined. Citric acid was the most effective on arable soil for lead and cadmium. Zinc was the most mobilized on arable soil by tartaric acid. Tartaric acid was more effective on meadow especially for lead [Fig.1]. Water soluble content of lead increased 2-6 fold, the same fraction of cadmium increased 2- 5 fold and water soluble zinc only 2 fold after the acids application. The highest changes in release of metals were determined for Pb > Cd > Zn. The stability of pH value for all variants were not expressively changed during
