Sažetak

Precipitation kinetics and adsorption behaviour in AgI colloid
systems prepared 'in statu nascendi' in the presence of non-ionic
surface-active agents of octaphenylethoxylate series were investigated by light scattering method at 20 CC. The rate of precipitation was followed directly by using light scattering photometel' with recorder. The adsorption isotherms exhibiting monelayer coverage in the regi on of maximum floceulation and multilayer adsorption in the stabilization region have been obtained.
The mechanism of floeeulation and stabilization can be assumed
considering several aggregation steps in the dependence of concentration and time.
