Abstract (en)

[origin: GB2318349A] A biocidal composition which, when associated with a surface is capable of controlling the accumulation of organisms/organic matter in an aqueous/humid environment at or near the surface, comprises a transition metal ion and a chelate binding to the metal ion, the composition being such that, in the presence of an oxygen source and preferably a reducing agent, it is capable of continuously generating a reactive oxygen species (eg a peroxide, superoxide or hydroxyl radical) in biocidal amounts, the metal ion being so firmly associated with the chelate that it does not dissociate into the aqueous environment. The surface may be eg a ship's hull, a water pipe, a rope, a filter or a medical bandage.
