Abstract

In order to find an effective and low-cost sorbent for the extraction of scandium from washing and waste solutions of a number of industries, we have researched sorption extraction of scandium from sulfuric acid solution of complex salt composition by spherically granulated titanium phosphate in the H+ form with a molar ratio of P:Ti=0.8-1.8 which was synthesized by sol-gel method (Institute for Sorption and Problems of Endoecology of National Academy of Sciences of Ukraine). It has been established that the sorbent with a molar ratio P:Ti=1.8 has the best sorption properties. We defined structural surface characteristics and ion exchange properties of the titanium phosphate. It is shown that it is advisable to use titanium phosphate when pH is less than 6. Static and kinetics of Sc (III) sorption was studied. We have requested the mathematical equation of scandium sorption isotherms on titanium phosphate. These data suggest that a titanium phosphate has not very high, but satisfactory sorption properties for the extraction of scandium from complex composition of sulfate solutions.
