Abstract: A method for removing nitrate ions from a solution is presented. The method includes providing a polymer comprising a protonated amine moiety and an anion derived from an acid having a pKa value greater than about 1. The method further includes contacting the polymer with the solution to bind at least a portion of the nitrate ions in the solution with the polymer, and form a polymer-nitrate complex. The method furthermore includes separating at least a portion of the polymer-nitrate complex from the solution.

Abstract: Methods for treating water containing dissolved solids, suspended solids, organic material, or combinations include contacting the water with a coated membrane comprising a coating material disposed on a membrane substrate, the coating material comprising structural units derived from a compound of formula I, a compound of formula II and a compound of formula III; wherein R1, R2, and R3 are, independently at each occurrence, C1-C12 alkyl; R4 is alkylsilyl; L1 is alkylurethanyl; L2 and L3 are, independently at each occurrence, alkyl; X is hydroxy, alkoxy, or alkylamino; and m, n, and p, independently at each occurrence, range between 4 and 9. The coated membrane is joined to a backing in membrane filtration apparatuses for use in the methods.
