Abstract

AbstractBy turbidimetric and electron-microscopic methods the influence of Pb(II)-EDTA on the physical ripening of silver bromide and silver chloride emulsions, obtained in excess of halide or silver ions, was investigated. The effect of Pb(II)- EDTA on the photosensitivity, S, the contrast, and the maximum density, Dm, was also studied. The reagent was found to perform as an active sensitizer when introduced at a concentration of 2 × 10-4 M prior to precipitation.Investigations on hypersensitization were carried out by a known method for hypersensitization with Pb(II)-EDTA. It was also shown that Pb(II)-EDTA can be applied in practice as a hypersensitizer as well as a sensitizer.
