Abstract: | Water solubilities (SW) determined by the HPLC generator column method are reported for a series of chlorinated dibenzo--dioxins (PCDDs) with SW ranging from 0.4 ng/L (ppt) for octa-chlorodibenzo--dioxin to 430 ng/L for 1,2,3,7-tetrachlorodibenzo--dioxin at 20°C. A correlation is demonstrated between SW and HPLC capacity factors (k′) for these extremely hydrophobic compounds, allowing calculation of SW of PCDDs from k′ and melting point data. |
