Abstract
A method of preparing a biocidal material comprises PA1 taking 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 which has been used for inhibiting microbial growth in an aqueous medium, PA1 extracting the biocide from the biocidal material with a solvent, and PA1 immobilizing the extracted biocide by hydrophobic exclusion on a support having a hydrophobic surface.
