ON THE STUDIES OP MOLYBDENUM (VI) SORPTION ON TITANIUM PHOSPHATE 'S ION EXCHANGERS

Mo (VI) sorption on the inorganic Ion exchangers on amorphous titanium phosphate and hydrous titanium dioxide was studied. The influence of solution acidity, Mo(VI) concentration In a solution, P:T1 mole ratio in a sorbent and the presence of various anions In solution was Investigated. Mo-contalnlng lonites, as a result of a sorption process, were studied for the purification of water and Ringer’s solution, contamlned with Cs 137 Ions. Obtained sorbents were examined In solutions with some transition metals and alkaline earth metals. Also IR spectrophotometry studies were carried out. It was found that the process of Mo (VI) sorption on titanium hydroxophosphate occurred mainly according to an anion exchange mechanism and did not Improve upon the ion-exchange properties of the Initial lonites. Obtained caesium uptake characteristics demonstrated the absence of surface heteropolycompounds in titanium hydroxophosphate treated by Mo(VI)-compounds.
