Methorics of the Precipitation Processes. XXV. Effects of Non-Ionic Surface-Active Agents on Growth and Aggregation of Silver Iodide 801s

Precipitation kinetics and adsorption behaviour in AgI colloid systems prepared \u27in statu nascendi\u27 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\u27 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
