Coordination compound that has the potential to be applied as a biocide for the prevention of algae and bacterial growth in water for industrial use. Tetrakis (hydroxymethyl) phosphonium sulfate (THPS) is an organophosphorus compound with low toxicity, biodegradability, and exceptional activity against microorganisms. Since this biocide is non-halogenated and is produced in a water solution, it does not generate VOC emissions. It's readily biodegradable by oxidative process, hydrolysis and interactions with light and/or organisms. It's also more efficient than traditional biocides, reducing the dose needed for successful treatment. Conventional treatment against microorganism growth in industrial water uses toxic, nonbiodegradable biocides.
