Atrazine-selective polymers prepared by molecular imprinting of trialkylmelamines as dummy template species of atrazine
Synthetic polymer receptors selective for atrazine have been prepared by molecular imprinting using trialkylmelamines as template molecules in place of atrazine. Trialkylmelamines were shown to be useful as templates for introducing affinity for atrazine into ethylene glycol dimethacrylate-methacrylic acid copolymers. The polymers showed the selective binding capacity for triazine herbicides including atrazine, whereas agrochemicals in other categories were not adsorbed to the imprinted polymers. The group selectivity demonstrated was comparable with that of the original atrazine imprinted polymers. Use of the nonagrochemical template molecules as a substitution to atrazine has made it possible to synthesize herbicide-receptor polymers free from troubles caused by analyte contaminants, which are desired for analytical applications.
