[The species of titanium in natural water].
The species of titanium in natural water was studied. Sample was filtered with a paper filter and a 0.45 micron membrane filter. The content of titanium in each case was determined by polarography proposed by Li, et al. It was found that the main species for all the tested samples was of the particle form. A supernatant of a river water sample was taken to study the effect of pH on the distribution of titanium species. It was found that pH was an important factor for species distribution. At pH1-2, the particle will change into the dissolved form in a short time; at pH 6-8, the dissolved form will change into the particle form in several days.
