“…A number of procedures have been developed in response to the need for an analytical method to determine silver halide ratios. Przybylowicz et al (2), Gerard et al (1), and Russel (3) have reviewed these techniques which include potentiometric titration with silver nitrate, automatic coulometric titration, polarography, X-ray spectrometry, neutron activation analysis, and activation analysis using a 252Cf neutron multiplier.…”
