N2 - • Adsorption of Sr by ethyl butyl phosphonate silica was demonstrated for the first time.• Hydrodynamic adsorption was possible, with reasonable capacity, at a high flow-rate.• Optimal operating pH and maximum adsorption capacity were quantified.• The silica shows greater capacity for Sr than for transition metals.• Evidence suggests that the silica matrix directly interacts with the adsorption process; not just the functional group.
