Abstract
A comparison of five different leaching/extraction tests, each characterized by different parameters such as liquid/solid ratio, pH, leachant, stirring conditions, duration time, has been performed on a highly homogenized fly ash reference material. Eight different elements (As, Cd, Cr, Cu, Ni, Pb, Se, Zn) have been considered in this study. The results show that, among all the considered experimental parameters, pH seems to have the greatest influence on metal release.Keywords
