ABSTRACT

The aim of this study was determine sorption properties of various modifications of titanium dioxide (TiO2) in the relation with their photocatalytic efficiency for the degradation of organic complexes. The samples included three commercial TiO2 samples and two laboratory preparations. Theoretical sorption capacities were determined from the titration curves of the samples. Dependences of distribution coefficients (KD) of strontium, cobalt, mercury and chromium on pH were measured in pH range 1–13 at volume of solution (V) to mass of absorber (m) ratio V/m=100. It has been concluded that for treatment of neutral to slightly acidic waste streams the most prospective absorber is the HTO sample that has satisfactory KD even at pH≈5 where it already exhibits high photocatalytic activity towards degradation of organic contaminants.
