| 摘要 |
A method for removing one or more organic or inorganic solutes from a solution, comprising contacting the solution with one or more layers of filtration media, whereby the solute(s) are adsorbed onto one or more filtration layer(s) is described. Primarily, but not exclusively, the filtration media are polymers formed by polymerizing one or more hydrophilic electrically active monomers, with the subsequent addition of varying mole percent's of one or more counter anions. The solution can comprise a polar solvent such as a polar organic solvent or water or an aqueous solution. The solution may also be a non-polar solvent, or water and organic mixture. The hydrophillic monomer can be, for example, a heterocyclic group, such as pyrrole or thiophene. The counter anion can be any anion, such as polystyrene sulfonate. The varying hydrophobicity or hydrophilicity of the polymer filtration media is controlled by the type(s) and mole percent of counter anion(s) used. |
