Abstract
The present invention relates to a composite material in which an active organic compound is dispersed, as well as to an effluent treatment process, especially a photographic effluent treatment process. The composite material comprises an aluminosilicate organic-inorganic polymer matrix in fiber form comprising at least on the surface an organic radical having a —SH or —S(—CH2)n—S— function with n between 0 and 4 and in which an active organic compound is dispersed.
Claims5
A method for treating a photographic processing bath of a photographic processing containing silver in ionic form which comprises contacting the bath with a composite material comprising an aluminosilicate organic-inorganic polymer matrix in fiber form comprising at least on the fiber surface an organic radical having a—SH or—SH(—CH2)nS—function wherein n is from 0 to 4 and having dispersed therein an active organic compound.
