Abstract
The present invention concerns a method of detecting cationic polymers comprising: obtaining a target water sample containing a cationic polymer; adding a polymer dispersant solution and a phosphate solution to the target water sample, the polymer dispersant solution is comprised of a polymer dispersant with calcium and magnesium hardness and the phosphate solution is comprised of a phosphate; standing the target water sample; and measuring the turbidity of the target water sample; comparing the turbidity of said target water sample with a calibration curve of the turbidity of samples containing known concentrations of cationic polymers to determine the concentration of cationic polymers in said target water sample.
