As(V) adsorption onto nanoporous titania adsorbents (NTAs): Effects of solution composition

► Very fast sorption kinetics of As(V) by NTAs. ► Higher removal of As(V) with Ti(25)-SBA-15 at pH 4. ► Higher removal of As(V) with MT at higher pH (7, 9.5). ► In the presence of phosphate, higher removal of As(V) by MT at low pH.
