Surface complex formation of K + , NO - 3 , SO 2- 4 , Ca 2+ , F -, Co 2+ , and Cr 3+ ions was determined on the surface of silica gel. Experimental data obtained by acid-base titration of suspensions were interpreted in terms of the triple-layer model. The value of the deprotonation constant of surf
