We investigated the As(III) and As(V) adsorption complexes forming at the γ -Al 2 O 3 /water interface as a function of pH and ionic strength (I), using a combination of adsorption envelopes, electrophoretic mobility (EM) measurements, and X-ray absorption spectroscopy (XAS). The As adsorption envel
