Abstract: Based on numerous latest references, the current developments in
surface complexation, surface precipitation and the corresponding models (SCMs
and SPMs), were reviewed. The contents involved comparison on surface charge
composition and layer-structure of solid-solution interface for the classical
1-pK and 2- pK models, In addition, the fundamental concept and relations of
the new models, i.e., multi-site complexation (MUSIC) and charge -distribution
(CD) MUSIC models were described as well. To avoid misuse or abuse, it must be
emphasized that the applicability nd limitation for each model should be
considered carefully when selecting the concerned model(s). In addition, some
new powerful techniques for surface characterization and analysis applied to
model establishment and modification were also briefly introduced.
