Fig. 1. Measured 14C activity inside and outside the dialysis membrane after 48 h of equilibration. A schematic high performance liquid chromatography with ultraviolet detection (HPLC–UV) chromatogram (254 nm, total run of 15 min) is presented in relation to the five collected fractions used in the 14C analysis. The first fraction contains the sum of trinitrotoluene and its degradation products (TNT*) bound to dissolved organic matter (DOM), the second and fifth fractions are unknown 14C, and the third and fourth contain TNT and aminodinitrotoluene (ADNT), respectively.
