Water solubility of 2,3,7,8-tetrachlorodibenzo-p-dioxin
Vacuum deposition of a solid film onto a glass surface and equilibrium on this film with water are the basis of a method that was used to measure the water solubility of 2,3,7,8-tetrachlorodibenzo-p-dioxin. Films of both /sup 14/C-radiolabeled and unlabeled dioxin were prepared so that solubilized material could be measured by radioactivity as well as by capillary GC/LRMS techniques. The averages of solubility values for radiolabeled and unlabeled dioxin were 3.9 x 10/sup -11/ M (12.5 parts per trillion) and 6.0 x 10/sup -11/ M (19.3 parts per trillion), respectively. The solubility values lie within the values predicted from Yalkowsky's K/sub ow/-solubility equation of best fit for chlorinated hydrocarbons and the available estimates for the octanol-water partition coefficient, K/sub ow/. 11 references, 2 tables.
