Method for determination of water treatment polymers
View Patent ↗A method for determining the presence and/or concentration of a water treatment polymer in an aqueous sample, comprising producing a polyclonal or monoclonal antibody to the water treatment polymer;, and using the antibody so produced as a reagent in an immunoassay, conducted on the aqueous sample.
1. A method for determining the presence and/or concentration of a polydisperse water treatment polymer in an aqueous sample, comprising (a) contacting a composition comprising an effective amount of a monoclonal or polyclonal antibody which binds to the water treatment polymer wherein the water treatment polymer is selected from the group consisting of a polymaleic acid polymer; a hydrolysed maleic acid polymer; terpolymers of maleic anhydride, ethyl acrylate and vinyl acetate; copolymers of acrylic acid and maleic anhydride; copolymers of maleic acid and sodium allyl sulphonate; copolymers of maleic anhydride and sulphonated styrene; and combinations thereof, with the aqueous sample; (b) incubating the sample with the composition comprising the antibody for a time effective for the antibody to bind to the water treatment polymer to form a complex; and (c) detecting the complex and thereby determining the presence and/or concentration of the water treatment polymer in the aqueous sample.
2. The method of claim 1 , wherein the aqueous sample is taken from water employed in plant cooling, steam generating plants, sea-water evaporators, reverse osmosis equipment, paper manufacturing equipment, sugar evaporator equipment, soil irrigation plants, hydrostatic cookers, gas scrubbing systems, closed circuit heating systems, aqueous-based refrigerator systems or down-well systems.
3. The method of claim 1 wherein the water treatment polymer is polymaleic acid polymer or hydrolyzed maleic acid polymer.
4. The method of claim 1 wherein the water treatment polymer is a terpolymer of maleic acid, ethyl acrylate and vinyl acetate.
5. The method of claim 1 wherein the water treatment polymer is a copolymer of acrylic acid and maleic acid.
6. The method of claim 1 wherein the water treatment polymer is a copolymer of maleic acid and sodium allyl sulphonate.
7. The method of claim 1 wherein the water treatment polymer is a copolymer of maleic anhydride and sulphonated styrene.
8. The method of claim 4 , wherein the terpolymer comprises a weight of less than about 1000 Daltons.
9. The method of claim 4 , wherein the ratio of maleic anhydride to ethyl acrylate or vinyl acetate is from about 2.5:1 to about 100:1.
