A method for water treatment, includes: contacting water with an effective amount of a composition comprising a polymer derived from a first monomer of formula I: (formula I), and a second monomer selected from : (formula), and (formula), to obtain a treated water with reduced chemical oxygen demand; and separating the treated water from the composition; wherein, a weight percentage of the first monomer to a total of the first and the second monomers is in a range of from 0 to 90%; R1, independently at each occurrence, is, H, C1-C18 alkyl, alkoxyl, or phenyl; R2 is C1-C18 alkyl, alkoxyl, or phenyl; and a is an integer ranging from 0-4. An associated composition and a method for preparing the same are also described. |
