    摘要: The present invention relates to a method for processing a color reversal photographic film that enables the amount of silver and tin (II) ions present in the washing water to be reduced, in order to obtain effluents that can be discharged to the drains and satisfy the regulations in force. The method according to the invention comprises the mixing with stirring of the washing water with a composite material comprising a polymer matrix in the form of an imogolite gel in fiber form comprising at least, on the fiber surface, an organic radical having an —SH function or an —S(—CH2)n—S— radical, with n between 0 and 4; the settling of said mixture, and the recovery of a supernatant having greatly reduced quantities of silver and tin (II) ions, enabling direct discharge to the drains.
