Anion resin include strong base/strong anion (SBA) and weak base/weak anion (WBA) resins:
NO3– — SBA resins removes this contaminant, but it must be regenerated early when the concentration of NO3– in the water is high.
CIO4– — Perchlorate can be removed with selective SBA resins which are single-use and/or regenerable.
Arsenic — SBA resins can only removed negatively charged arsenate (HASO42-), which is related to arsenic in water. Since arsenite is usually neutral in aqueous solution, pre-oxidation is necessary, then the residual must be removed.
Total organic carbons (TOCs) — SBA resin is typically used to remove DBPs cause by TOCs that can be oxidized by secondary chlorine disinfection. These are regulated by the EPA.
Uranium — SBA resin can remove this contaminant, usually found as anionic uranyl carbonate/sulfate complexes.
