Sorption of Heavy Metals in Organic Horizons of Acid Forest Soils at Low Added Concentrations

Popis výsledku v původním jazyce

The individual adsorption/desorption of Cu, Pb and Zn in six soil samples taken from orgnic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of the varying extent of their sorption to the soil organic matter. The initial concentration range for all metals is 0-200mg/l. 0.01 mol/l Ca(NO3)2 was used as the background electrolyte. Soil samples were taken at random locations throughout a relatively small area and are characterized by small differences in mineralogical composition. Organic matter content and pH of soils are considered as the key factors causing differences in sorption/desorption behaviour of selected metals. In general, the sorption of all the three metals increased with a combination of higher pH value and increasing organic matter content. Copper sorption seems to reflect mainly the differences in organic matter content in addition to the differences in pH. The average amount of sorbed Pb was approximately 90%, Cu sorption averaged 60
