The AF-XX-3207 filter is highly effective at removing low levels of uranium from water, especially within a pH range of 6 to 8.2. At pH levels above 6, uranium forms a carbonate complex that strongly binds to the AF-XX-3207 filter. This filter exhibits exceptional uranium retention, surpassing its affinity for sulfate and other common anions. Additionally, its high capacity ensures that uranium remains securely bound, even in the presence of other anions and organic substances during operation.
