A method of preparing a biocidal material

摘要

A method of preparing a biocidal material comprises taking a biocidal material comprising a biocide having a log P value of at least 1.5 immobilised by hydrophobic exclusion on a support having a hydrophobic surface which has been used for inhibiting microbial growth in an aqueous medium, extracting the biocide from the biocidal material with a solvent, and immobilising the extracted biocide by hydrophobic exclusion on a support having a hydrophobic surface.
