Water disinfection method using metal-ligand complexes
First Claim
1. A method for disinfecting contaminated natural water, comprising the steps of formulating a solution comprising at least one biocide metal bound to at least one complexing agent taking into account competition between other known cations and anions in the contaminated natural water and the at least one biocide metal, adding the solution to the contaminated natural water such that the at least one biocide metal remains in solution, and obtaining potable water from the contaminated natural water to which the solution has been added.

Abstract
Metal-ligand complexes produced by coordination chemistry for use as a biocide and a method for detoxifying water or effluent are disclosed. Metallic biocides are bound with acceptable complexing agents as a type of coordination compound to shield the metal ions from other reactants in the water supply being treated while keeping the metal ions available for biocidal action. In particular, pre-mixed solutions of metal-ligand complexes are added as a disinfectant to water containing ions such as calcium, iron, carbonates, chlorides, nitrates, phosphates, and sulfates.
