Synthesis and Characteristic of Nitrate-Selective Ion Exchange Resins
Nitrate-selective ion exchange resins have been synthesized by the reaction of chloromethylated polystyrene - divinylbenzene copolymer and corresponding trialkyl amine [NR3 = NEt3 [N(CH2CH3)3](2), NPr3[N(CH2CH2CH3)3](3), NBu3[N(CH2CH2CH2CH3)3](4), NPe3[N(CH2CH2CH2CH2CH3)3](5) in ethanol. The functional group of ion exchange resin for the effective NO3- removal was the order of NPr3 > NBu3 > NEt3 > NMe3 > NPe3.
