Abstract [en]

Old glassworks siteshave been always associated with contamination by different trace elements likePb, Cd, As, Zn and others. The mixture of soil and waste glass of particlesizes <2mmat one of the oldest Swedish glassworks (the Pukeberg) was studiedby analyzing the trace elements content, organic content (3.6%) and pH (7.4).The results showed hazardous concentrations of Pb (1525 mg/kg), Ba (1312mg/kg), Sb (128 mg/kg), Cd (36 mg/kg), As (118 mg/kg), Zn (1154mg/kg) and Co(263 mg/kg) exceeded the Swedish guidelines of contaminated soil. Batchchemical extraction by the chelating agents EDTA, DTPA and the biodegradableNTA were performed to study the effect of chelating agent concentration and mixingtime on the extraction efficiencies by following a Box-Wilson design ofexperiments. The results displayed good extraction efficiencies (less than 41%)of Pb, Cd, As and Zn by the EDTA, DTPA and NTA, which seemed depends on thetype of chelator. In addition, high correlation between the extraction efficiencies,the chelators concentration and mixing time was found based on the statisticaland experimental results.
