Use of Hydrophilic Insoluble Polymers in the Restoration of Metal-Contaminated Soils
Copper and manganese removed from a polyacrylate polymer* with different solutions.
Ratio of COOH groups
Cu removed (%)
Mn removed (%)
Solution : Polymer
2 M KCl
*Polymer was expanded in 5 mM CuSO4 or MnSO4 for 48 hours, excess water removed by filtration, and the polymer was left to equilibrate with the different solutions for 72 hours. These were filtered and the amount of Cu and Mn was analyzed in the filtrates by atomic absorption spectrometry.
