Surface complex formation at the adsorption of Cu2+ ions and 2,2'-bipyridine onto highly disperse silica

The enhanced adsorption of copper ions onto silica surface from the solution containing 2,2'-bipyridine is explained by ternary surface complex formation. The equilibrium reaction constants of binary and ternary complexes have been calculated using constant capacitance model. The potentiometric...
