Jieyuan’s paper describing a systematic exploration of the way specific inorganic ions and humic acid effect PFAS adsorption on activated carbon (AC), anion exchange resins (AER), and two novel StyDex polymers has been published in Water Research!

Jieyuan found that the pattern of adsorption inhibition of both StyDex polymers were similar to each other but different from AC and AER, which demonstrates the distinctive PFAA adsorption mechanism on StyDex polymers. The unique performance of each type of adsorbent confirms unique adsorption mechanisms that result in unique patterns of adsorption inhibition in the presence of matrix constituents. These insights could be used to develop models to predict the performance of these adsorbents in real water matrices and afford rational selection of adsorbents based on water chemistry for specific applications
