A method of preparing a copper complex to be used in eliminating the growth of aquatic or marine plant life, such as algae. The copper complex is formed by reacting finely divided water-insoluble copper carbonate with the combination of monoethanolamine and triethanolamine. The copper compound is completely solubilized and complexed by the combination to provide a copper complex having improved stability and containing an increased amount of elemental copper as compared to copper complexes formed by prior methods, thereby making the complex more effectiv...
An algaecide comprising an aqueous solution containing an algaecidal effective amount of a water soluble copper complex produced by mixing finely divided water insoluble copper carbonate with the combination of monoethanolamine and triethanolamine, said monoethanolamine being present in a molar ratio slightly in excess of 2:1 with respect to the copper concentration and the triethanolamine being present in a molar ratio slightly in excess of 1:1 with respect to the copper concentration, said combination acting to completely solubilize and chelate the cop...
