Abstract

Abstract: The surface area and crystal hibit of an AgBr dispersion were determined by a in situ method. In this method, the difference of the absorption spectra of an cationic cyanine dye Ⅰ in adsorption and solution state was used for the measurement of AgBr surface area. It was 17.1 m~2/g AgBr. And the crystal habit was determined hased upon the absorption spectra of an other two cyanine dyes (Ⅱ and Ⅲ) in adsorption state. It showed a cubic crystal.

Key words: Adsorption, AgBr dispersion, Surface area, Crystal habit
