The solubility of 2,6-dinitrotoluene 2,6-DNT, 2,3-dinitrotoluene 2,3-DNT, 4-nitrotoluene NT and 1,3,5-trinitrobenzene TNB was measured in seawater with ionic strength 0.1662, 0.3352, 0.5071, and 0.6820 molL and pure water at temperatures between 277 and 314 K. The pure water solubility values compare well with values reported previously. The solubility in seawater was lower than that in pure water. The average salting-out coefficients for NT, 2,6-DNT, 2,3-DNT, and TNB were 0.15, 0.12, 0.13, and 0.09 Lmol, respectively, which are consistent with measurements for other nitroaromatic compounds. The salting-out coefficients did not show any significant variation with temperature over the range examined.
