Poly(sodium acrylate) hydrogels as potential pH-sensitive sorbents for the removal of model organic and inorganic pollutants from water
General
Anionic poly(sodium acrylate), PANa, hydrogels bearing negatively charged –COO- groups were used as sorbents for the removal of colored organic or inorganic model pollutants, namely Crystal Violet and Cu2+, from water. It was found that PANa hydrogels adsorb stronger Cu2+ions than Crystal Violet, as...
