The removal of five heavy metals was evaluated in vertical downflow column, with a granitic residual soil, operated in discontinuous and continuous mode. The results show higher removal rates of the five metals for the continuous mode, with highest values to Zn and Pb followed by Ni, Cu and Cr. The removal of all metals occurs mainly at the top 5 cm essentially through complexation and precipitation in the form of hydroxides.
