What Are the Limitations of Ion Exchange in Toxicology?
While ion exchange is a powerful tool, it has limitations. The selectivity of the resin for certain ions can vary, meaning it might not effectively remove all toxic ions present. Also, resins can become saturated and need regeneration, which involves using a strong acid or base solution to replenish their ion-exchanging capacity. This regeneration process can be costly and environmentally hazardous if not managed correctly.
