Isotope Exchange (IE) and XAS techniques combined are a powerful analytical tool. IE and XAS delineate chemically-labile As-forms, -sorbed and/or –free precipitates. Aging time is an important factor in determining the labile As in soil. SEM analysis confirms free precipitates of Al-, and Fe-arsenates.
