Dried ground formaldehyde‐treated peanut skins, white ash bark, and So. Wisconsin red maple bark are efficient substrates for removal of many heavy metal ions from waste streams, but possible interference by common light metal cations has never been determined. The influence of Ca 2+ , Mg 2+ , or Na + on the removal of the heavy metal ions Pb 2+ , Cu 2+ , Cd 2+ , and Zn 2+ by the above substrates was studied in both batch and packed‐column experiments. It was found that Pb 2+ and Cu 2+ were minimally affected by the presence of these light metal ions in solution, while the uptake of Cd 2+ and Zn 2+ was significantly reduced. Calcium ion produced the greatest effect of the light metals tested.
