Abstract
Methods for removing contaminants from aqueous media using polyelectrolyte complexes having a heterogeneous charge distribution are provided. The polyelectrolyte complexes are formed from an amphiphilic anionic random copolymer and a cationic random copolymer are provided. The polyelectrolyte complexes absorb cationic, anionic, or hydrophobic organic molecules and can be easily removed from water.
