Impact/Purpose:
This study uses batch experiments to examine the kinetics and equilibria of sorption of two anionic dyes, metanil yellow and indigo carmine, by strong base ion exchange resins that are commonly studied for treatment of PFAS in drinking water. Results of the batch experiments are used in conjunction with a previously developed anion exchange column performance model to assess the viability of the dyes as proxies for PFAS in water treatment systems. This presentation is expected to be of interest to water treatment scientists and engineers developing bench and pilot-scale ion exchange performance trials.
