摘要：

A procedure for conducting adsorption studies at low suspended solid concentrations in natural waters ( less than 50 mg l** minus **1) is described. Methodological complications previously associated with such experiments have been overcome. Adsorption of zinc ion onto synthetic colloidal titania (TiO//2) was studied as a function of pH, supporting electrolyte (NaCl) concentration (0. 1-0. 002 m) and particle concentration (2-50 mg l** minus **1). The lack of success of the Davis Leckie site bonding model in describing Zn(II) adsorption emphasizes the need for further studies of adsorption at low suspended-solid concentrations.
