Název v původním jazyce

Biochar application to metal-contaminated soil: Evaluating of Cd, Cu, Pb and Zn sorption behavior using single- and multi-element sorption experiment

Popis výsledku v původním jazyce

The aim of this study was to evaluate Cd, Cu, Pb and Zn sorption behavior after biochar application into a contaminated soil. Two different types of biochar originated from the same organic material (contaminated and uncontaminated) at different application rates (1% and 2% w/w) were evaluated. Batch sorption/desorption experiments were established using single- and multi-element solutions. Zinc was easily desorbed in the presence of Cu, Pb. Desorption was reduced after biochar application. Results proved the different sorption behavior of metals in the single-metal solution compared to the multi-metal ones due to competition effect. Moreover, during multi-element sorption, Zn was significantly desorbed. The applied biochar enhanced Cu and Pb sorptionand no changes were observed when contaminated and uncontaminated biochar was used. Furthermore, the application rate had no effect as well. Finally, applied rates of biochars were insufficient for metal immobilization in such contaminate
