Metal oxide of titanium was deposited on native Jordanian diatomaceous clay. The chemical and structural properties of the modified and the unmodified samples were characterized by XRF, XRD, SEM and FTIR techniques. The diatomaceous clay supported titanium oxide was used in preliminary experiments to study the interactions with aniline, N-methylaniline, and N,N dimethylaniline in aqueous solution .The results showed that titanium oxide interacted with diatomaceous clay and caused some structural changes. These were reflected in the surface area of the samples and their activity in the removal of aniline and its derivatives from aqueous solutions . The removal rate of aniline and its derivatives decrease with the increase of pH. Adsorption isotherms of modified diatomaceous clay indicates that aniline and its derivatives follow type 1, which is the Langmuir isotherms.
