The invention relates to products, containing a solid biocide and a composite material (11) for the absorption of contaminants and the release of active ingredients as a composite preparation for the simultaneous, separate or programmed sequential application on sterilization and long-term conservation of a liquid (6) for purification. According to the invention, the activity of the solid biocide can be maintained by additionally treating the liquid (6) with the composite material (11), which absorbs (5.1, 5.2) from which the liquid and/or contaminants simultaneously releases active ingredients (13.1, 13.2) for sterilizing and/or reducing the contaminants (5.1, 5.2) in the liquid (6). The products and the method are particularly suitable for sterilizing and long-term conservation of water/oil emulsions which are contaminated by sulphur-containing compounds.
A product, comprising a mixture of a solid biocide granulate and a composite material in granulate form, which composite material comprises a hydrogel substrate and incorporates and/or has bonded therein a silver (Ag) complex as an active ingredient, as a combination preparation for the simultaneous application during a sterilization and long-term preservation of a fluid to be purified,
