Use of Hydrophilic Insoluble Polymers in the Restoration of Metal-Contaminated Soils
Figure 2
Dehydration of polyacrylates in the presence of different cations: (a) water absorption by a polyacrylate polymer after equilibration with 0.01 M salt solution, filtration, and reequilibration with de-ionized water, (b) a polyacrylate polymer in the presence of increasing concentrations of Cr3+ (above) or Cu2+ (below).
