Use of a composite material for the remediation of contaminated water by micro-organisms, is claimed, where the material comprises: (I) at least one type of alumina as a porous support (80-99.8 wt.%); (II) at least one assistant material (0.1-10 wt.%) deposited on the support (I) and comprising titanium oxide, compounds containing phosphate anion, molybdenum trioxide, silicon dioxide, boron trioxide, chromate ions or dichromate ions; and (III) at least one active phase (10-40 wt.%) deposited on the layer of assistant material (II). Use of a composite material for the remediation of contaminated water by micro-organisms, is claimed, where the material comprises: (I) at least one type of alumina as a porous support (80-99.8 wt.%), which has a surface area of at least 250 m 2>/g and a porosity of at least 0.65 m 3>/kg; (II) at least one assistant material (0.1-10 wt.%) deposited on the support (I) and comprising titanium oxide, compounds containing phosphate anion, molybdenum trioxide, silicon dioxide, boron trioxide, chromate ions or dichromate ions; and (III) at least one active phase (10-40 wt.%) deposited on the layer of assistant material (II), and the active phase comprises one or more oxides, or water-insoluble salts, transition metals comprising cations of silver, nickel, copper, cobalt, iron or manganese. |
