New paper published in Water Research in collaboration with Helmholtz Centre for Environmental Research (Navid Saeidi & Anett Georgi). Electrosorption is an emerging approach for removing and concentrating trace organic contaminants from water, including PFAS and pharmaceuticals, by combining conductive adsorbents with electrical control. This Making Waves article argues that such systems should not simply borrow terminology and performance metrics from capacitive deionization, because trace-organic removal is often governed by adsorption affinity, selectivity, pore accessibility, and controlled release rather than charge-storage capacity. We propose a clearer terminology and reporting framework centered on metrics such as adsorption coefficients, breakthrough behavior, recovery, and enrichment to support better comparison between studies and accelerate the rational design of electrosorption technologies for water treatment.
