三甲胺是一种基于聚苯乙烯的季铵盐型阴离子交换树脂脱酸FF的γ辐射分解的主要产物。在辐照的干树脂G(Me3N)=4·0-4·4和糊状态(树脂：水=1：2，w/w)中，G(Me3N)=3·2。当样品被电子清除剂(N2O，H+，NO3-)溶液糊化时，G(Me3N)值降低。结果表明，浆液树脂的脱氨既有直接辐解作用，也有浆液水辐解产生的水合电子反应的作用。
Trimethylamine is a major product of the γ-radiolysis of De-Acidite FF, a polystyrene-based, quaternary ammonium anion-exchange resin. In the irradiated dry resin G(Me3N)= 4·0–4·4 and in the slurried state (resin:water = 1 : 2, w/w)G(Me3N)= 3·2. When the samples were slurried with solutions of electron scavengers (N2O, H+, NO3–) decreased values of G(Me3N) were obtained. The results suggest that the slurried resin is deaminated both by direct radiolysis and by the reaction of hydrated electrons produced by the radiolysis of the slurrying water.
