Disclosed is a method of removing anionic pollutants from wastewater, comprising contacting said wastewater with an anion-binding polymer, whereby said anionic pollutants are absorbed to said polymer. Also disclosed is a method of removing anionic pollutants from wastewater and providing an agricultural fertilizer, comprising contacting said wastewater with an anion-binding polymer, whereby said anionic pollutants are absorbed to said polymer, eluting the anionic pollutants from said polymer with a strongly alkaline solution, and neutralizing the eluant, whereby an agricultural fertilizer is obtained. Preferred anion-binding polymers are hydrogels such as cross-linked poly(allylamine). Also disclosed is a method of treating hyperphosphatemia in a patient with the hydrogels of the present invention. |
