What is Effect of 2,2′-Bipyridine on the Adsorption of Zn2+ Ions onto Silica Surface about?
The influence of 2,2 -bipyridine (bipy) on adsorption of zink ions onto a highly dispersed silica surface has been studied. The enhanced adsorption of zink ions onto silica surface from the solution containing 2,2 -bipyridine is explained by ternary surface complex formation, {≡SiOH -m Zn(bipy) (2-m)+ n }. The adsorbed Zn 2+ and bipy concentrations were measured at the adsorption from solutions with different ratios of Zn : bipy. The equilibrium reaction constants of binary and ternary complexes have been calculated using the constant capacitance model. The potentiometric titration data were used in order to determine the H + /Zn 2+ exchange stoichiometry. The composition of formed surface complexes has been confirmed with their UV absorption spectra.
