Batch and stirred flow reactor experiments on Zn sorption in acid soils

The adsorption and desorption of zinc in acid soils developed over granite and amphibolite were investigated with and without the simultaneous addition of copper. In stirred flow experiments, the maximum Zn sorption capacity (qmax) ranged from 1.29 to 4.36 mmol kg−1, and was significantly correlated (r = 0.924; p
