Fig. 2. Degradation of aqueous TNT (0.22 mM) in dark- or light-Fenton reactions: dark, pH 3 (•); light, pH 3 ( ${triangledown}$ ); light, pH 7 (Fe³⁺ to nitrilotriaceticacid [NTA] ratio = 1:1) ( ${blacksquare}$ ); dark, pH 7 (Fe³⁺ to NTA ratio = 1:1) ( ${circ}$ ); light, pH 7 (Fe³⁺ to NTA ratio = 1:10) ( ${square}$ ); dark, pH 7 (Fe³⁺ to NTA ratio = 1:10) ( ${blacktriangledown}$ ). See text for description of dark- and light-Fenton reactions. Error bars on symbols indicate standard error of means (n = 3, P $<=$ 0.05); where absent, bars fall within symbols.
