Název v původním jazyce

Leaching of heavy metals stabilized in asphalt matrix

Popis výsledku v původním jazyce

Long-term impact of stabilized/solidified hazardous waste on the environment was evaluated using a combination of long-term leaching tests and mathematical modelling. The waste used in this research is a dust collected from filters used in the productionof nickel-cadmium accumulators. It contains nickel hydroxide, cobalt hydroxide and cadmium oxide, and based on Toxicity Characteristic Leaching Procedure (TCLP) test it is a hazardous waste. This waste was stabilized using two different aqueous anionicasphalt emulsions. Several extraction tests were used to evaluate the long-term leaching of stabilized waste. Then using a mathematical model, the long-term leaching test data was analyzed to obtain mass transport parameters for the contaminants in the stabilized wastes. From the leaching test results mathematical model parameters needed to estimate the transport and release of contaminants to the real environment under alkaline pH from the stabilized waste were obtained. The model simul
