CADMIUM-SULFIDE PARTICLES IN ORGANOMONTMORILLONITE COMPLEXES

Cadmium sulfide (CdS) particles have been generated by the infusion of hydrogen sulfide into cadmium-salt-containing organomontmorillonite c omplexes dispersed in ethanol-water, ethanol-benzene and ethanol-cyclo hexane mixtures. Montmorillonites ion exchanged to different extents b y octadecylammonium and hexadecylpyridinium salts have been used as or ganomontmorillonite complexes. CdS formation has been examined as a fu nction of the extent of surfactants present in the organomontmorilloni te complexes, the composition of the solvents, and the concentration a nd type of cadmium salts used, Absorption and emission spectrophotomet ry, differential thermal analysis, dynamic laser light scattering and X-ray diffractometry have been utilized for monitoring CdS formation.
