Zusammenfassung:Anion exchange resins including at least two positively charged sites and a well-defined spacing between the positive sites are provided together with a process of removing anions or anionic metal complexes from aqueous solutions by use of such resins. The resins can be substituted poly(vinylpyridine) and substituted polystyrene. Las resinas de intercambio anionico que incluyen al menos dos sitios cargados positivamente y un espaciamiento bien definido entre los sitios positivos se proporcionan junto con un proceso para eliminar los complejos metálicos anionicos o los aniones de las soluciones acuosas mediante el uso de tales resinas. Las resinas pueden ser poli(vinilpiridina)substituida y poliestireno substituido.
