FIG. 2.

The rapid formation of N-chloroamino acids (255 nm) upon addition of Viking LR organics to gamma-irradiated Ca(ClO₄)₂ in aqueous solution (• 0 s; ▴ 0.16 s; ▪ 0.32 s). The absorbance by ClO⁻ at 290 nm decreases as N-chloroamino acids form (260 nm). The absorbance by ClO₂ (g) at 360 nm is attenuated due to dilution by the addition of the LR organics. No reaction between the LR organics and ClO₂ (g) is observed. The LR aqueous organic solution contains sodium formate, D-alanine, L-alanine, sodium D-lactate, sodium L-lactate, glycine, and calcium glycolate, each at a concentration of 2.5×10⁻⁴ M.
