METHOD OF CONTROLLING ALGAE IN A BODY OF WATER
A method of treating algae in a body of water is disclosed. The method includes adding an amine compound to the body of water in amounts≦4 parts per million as an effective algaecide.
1 . A method of controlling algae in a body of water, said method comprising adding an amine or a salt of an amine having general formula (1)
or a salt thereof
wherein
R 1 is a substituted or unsubstituted C 6-30 alkyl; and
R 2 and R 3 are each independently a hydrogen atom, a substituted or unsubstituted hydrocarbyl group having between 1 and 20 carbon atoms, to the body of water in an effective amount to control the growth of algae in the body of water up to 4 or less parts per million.
2 . The method according to claim 1 , wherein the hydrocarbyl group is a straight chain hydrocarbyl group having between 2 and 20 carbon atoms.
3 . The method according to claim 1 , wherein R 1 is a C 8-16 alkyl group and R 2 and R 3 are each a hydrogen atom or amine substituted hydrocarbyl group having between 1-6 carbon atoms.
4 . The method according to claim 3 , wherein R 1 is a C 12 alkyl group and R 2 and R 3 are each a hydrogen atom.
5 . The method according to claim 3 , wherein R 1 is a C 12 alkyl group and R 2 and R 3 are each —CH 2 —CH 2 —CH 2 —NH 2 .
6 . The method according to claim 1 , wherein the amine is a hydrochloride salt.
7 . The method according to claim 1 , wherein the amine is used in an amount between 0.001 and 2.0 ppm (mg/l).
8 . The method according to claim 9 , wherein the amine is used in an amount between 0.01 and 1.8 ppm (mg/l).
9 . The method according to claim 1 , further comprising adding an additional algaecide to the body of water.
10 . The method according to claim 9 , wherein the additional algaecide comprises a copper-based algaecide.
11 . The method according to claim 9 , wherein copper-based algaecide is mixed with the amine or salt of the amine to form a mixture of algaecides and the mixture of algaecides is added to the body of water.
12 . The method according to claim 1 , further comprising adding an herbicide to the body of water.
13 . The method according to claim 12 , wherein the herbicide is mixed with the amine of salt of the amine to form a mixture, and the mixture is added to the body of water.
14 . The method according to claim 1 , wherein the amine or salt of the amine is mixed with an herbicide, a colorant, an adjunctive, another algaecide, a solvent or a mixture thereof.
15 . The method according to claim 1 , wherein the body of water is earth surface water.
16 . The method according to claim 15 , wherein the surface water is a lake, a pond, or a canal.
17 . The method according to claim 16 , wherein the amine or amine salt is added in an amount of 0.01 to about 1.0 ppm, R 1 is a C 12 alkyl group and R 2 and R 3 are each —CH 2 —CH 2 —CH 2 —NH 2 .
