PULSED RADIOLYSIS STUDY OF FORMATION OF THE DISPERSE PHASE OF AGCL INAQUEOUS-SOLUTIONS

The formation of the disperse phase of AgCl in aqueous solutions conta ining organochlorine compounds as additives was studied by pulsed radi olysis. It was shown that attenuation of light is only due to scatteri ng on colloidal particles of (AgCl)m. The Rayleigh law (D approximatel y lambda-n) is satisfied for the optical spectra. The values of n decr ease from 4 to 3 with an increase in D, which indicates an increase in the average particle size from less-than-or-equal-to 50 to approximat ely 140 nm. The composition of the solution (its ionic strength in par ticular) significantly affects the formation and stability of the disp erse phase.
