Figure 1From: Ionizing radiation induced degradation of diuron in dilute aqueous solutionTransient absorption spectra in N2O saturated, 1 × 10−4 mol dm−3 diuron solutions. Closed symbols in the absence, open symbols in the presence of 1 × 10−4 mol dm−3 K3Fe(CN)6, dose/pulse 20 Gy. Inset: concentration dependence of pseudo-first-order rate constant of absorbance build-up at 325 and 365 nm.Back to article page
