Adsorption Behavior of PFASs to 44 Inorganic and Organic Sorbents and use of Dyes as Proxies for PFAS Sorption
Journal of Environmental Chemical Engineering, Volume 8, Issue 3

SUMMARY
This study was totally independent and performed by a world class research group at the Swedish University of Agricultural Sciences.
44 sorbents were tested for their binding capacity to PFAS.
RemBind® was the most competitive sorbent of the 44 sorbents tested in terms of price and PFAS binding strength.
The top 5 sorbents (including RemBind®) were all carbon-rich and had significantly higher PFAS binding strengths than the other 39 sorbents tested. They adsorbed >99% of all 17 PFASs tested.
An independent price analysis in Europe showed that the other 4 carbon-based sorbents were either not available commercially or were very high-grade carbons that are significantly more expensive than RemBind®.
This proves that only very high-grade carbons can compete with RemBind® for PFAS binding strength and they do not currently compete with RemBind® on price.
