Notes	Two surface soil samples were collected from each of alluvial soils and grey degraded soils in Hanoi City, Vietnam and subjected to soil chemical and physical analyses and to a batch adsorption test for evaluation of the adsorption capacity of heavy metals such as Cu, Pb, Zn and Cd. The results showed that the alluvial soil had the high organic matter, free iron oxides, clay and active 2:1-type silicate minerals contents, and high pH value in comparison with those of the grey degraded soil. The adsorption isotherm of heavy metals by the soils was well fitted to the Freudlich model. The adsorbents for heavy metals as a total of organic matter, free iron oxides, and clay minerals in terms of both amount (clay content) and type (clay mineralogical composition) were larger for the alluvial soil than for the grey degraded soil. As a result, the adsorption capacity of heavy metals was distinctly higher for the former than for the latter. Within a soil, the adsorption capacity was decreased in the sequence of Pb＞＞Cu＞Zn for the alluvial soil and of Pb＞＞Zn＞Cu for the grey degraded soil.
