Applicability of micro-PIXE analysis to quantitative evaluation of heavy elements sorbed on minerals was investigated to get better understanding of sorption and distribution of heavy elements onto mixture of minerals in soil. For this, external standards, that is, heavy element-sorbing minerals of uniform shape and size, were analyzed by micro-PIXE. It was found that such external standards were available to quantitative evaluation by micro-PIXE though their applicability may be limited.
