Additional information

In water, titanium tetrachloride rapidly hydrolyses to titanium dioxide and hydrochloric acid. Hydrochloric acid is not expected to adsorb, due to its high solubility in water. The partitioning of titanium between suspended particulate matter and water was investigated by Veselý et al. in czech river water. Although elemental titanium was analysed, the titanium was probably present in form of titanium dioxide. Field-based distribution (partition) coefficients, Kd, between suspended particulate matter (SPM) and filtrate ('dissolved' fraction) were determined. For titanium a logKd of 2.36 was obtained (Veselý et al., 2001). Roychoudry and Starke investigated the partitioning of titanium between sediment and water in a South African wetland, and determined a logKd of 4.61 (Roychoudry and Starke, 2006)
