1. A method comprising:
exposing a substance in need of contaminant remediation to a plurality of macroparticulates having an average particle size of about 1 mm or more;
wherein the macroparticulates are free particles and comprise a reaction product of an epoxide-containing (meth)acrylic polymer or copolymer and a compound bearing a nitrogen nucleophile comprising at least one amine;
wherein the epoxide-containing (meth)acrylic polymer or copolymer comprises about 99 wt. % or greater glycidyl methacrylate; and
wherein the epoxide-containing (meth)acrylic polymer or copolymer is formed from glycidyl methacrylate, diethyleneglycol dimethacrylate, and tris(2-(acrylolyloxy)ethyl)isocyanurate;
forming contaminant-laden macroparticulates by adsorbing or bonding a contaminant from the substance in need of contaminant remediation onto a surface of the macroparticulates; and
separating the contaminant-laden macroparticulates from the substance in need of contaminant remediation.
