Biocide material and method of preparation of said material

Method of preparing a biocidal material

A method for inhibiting the growth of microorganisms in an aqueous medium comprises contacting the aqueous medium with a permeable body comprising material which interacts with the microorganisms. Such interaction involves a change in the chemical structure of the material resulting from the action of one or more of the microorganisms. The permeable body may take the form of a permeable bag containing plant fibers and may be used for the treatment of photoprocessor wash waters.

Method for inhibiting the growth of microorganisms in an aqueous medium

A method of inhibiting microbial growth in wash water contained in a photoprocessing system. The method comprises placing in the wash water an apparatus comprising a pump with an attached permeable container and an inlet and outlet means for the wash water. The permeable container includes a biocide immobilized on a support. The wash water as it is pumped through the pump passes through the container and makes contact with the immobilized biocide in order to inhibit microbial growth in the wash water. The apparatus is self-contained and may be placed in a reservoir of an aqueous medium to be treated.

Apparatus and method for inhibiting microbial growth in an aqueous medium

A method of inhibiting microbial growth in an aqueous medium comprising contacting the aqueous medium with a biocidal material comprising a biocide having a log P value of at least 1.5 immobilized by hydrophobic exclusion on a support having a hydrophobic surface, characterized in that contact is made in the presence of a potentiating agent for the biocide.

Method of inhibiting microbial growth in an aqueous medium

A biocidal material comprises an organic biocide immobilised on a polymeric support characterised in that the support is water-insoluble and the biocide is covalently bound to the support by a hydrolytically stable covalent linkage. The material can be used for inhibiting bacterial growth in an aqueous medium e.g. the wash water of a photoprocessing system. The material can be housed in a flow-through container.

A biocidal material comprises a biocide immobilized in a porous inorganic polymer network such as a sol-gel matrix. The polymer may be coated on an inorganic support. The material can be used for inhibiting microbial growth in an aqueous medium, e.g., the wash solution of a photoprocessing system. The material can be housed in a flow-through container.
