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, {β‘SiOH -m Zn(bipy) (2-m
The hydrodynamic radii of colloidal silica particles in the aqueous solutions were measured under various conditions of \(\mathrm{pH}\) and salt concentration by means of the dynamic light scattering technique. In the salt free solutions the observed hydrodynamic radius increased by \(1 \mathrm{~nm}
