The objective of the research was to determine if activation analysis could be used to investigate coagulation-flocculation reactions. Experimental study of the coagulation-flocculation reaction was developed by preparing clay-water mixtures using montmorillonite and illite clay samples and a standard ionic solution. Samples of the clay material were subjected to neutron activation for various times and neutron flux values. The irradiated clay samples were blended with stable clay materials and subjected to electrophoresis. Results of this study showed that clay minerals can be activated to a high value by thermal neutron irradiation and that the neutron irradiation can be controlled to increase the yield of specific radionuclides. Experimental results also showed that the clay particle migrated as a integral unit particle during electrophoresis. (Author)
