Copper based algaecides and aquatic herbicides |
摘要 |
Basic copper salts such as cupric hydroxide, basic copper chloride, basic copper sulfate and the like with an alkanolamine result in an unexpectedly beneficial composition useful in a method for treating bodies of water to arrest or eliminate the growth of algae and aquatic weeds; a more stable and less corrosive solution is obtained for storage purposes when the insoluble basic copper salts are reacted with an alkanolamine such as trialkanolamine or mixtures or tri- and dialkanolamines to produce a water soluble copper complex of the organic compounds; moreover, the formed complex of the insoluble basic salts provides a higher copper content in the solution formed by the complex when compared to the acid, water soluble copper salts; full effectiveness of the complex has been observed for extended period of time without decrease of soluble copper content.
