Titanium Recovery from its Aqueous Media by 3-Acetylpentane-2,4-Dione as Reagent

ABSTRACT 3-acetylpentane-2,4-dione (AD) was synthesized and characterized using elemental analysis and IR spectroscopy, in order to examine it as an extractant for recovery of titanium from aqueous acidic media. Various factors, which affect recovery procedure as nature of acids, titanium concentration, acid concentration, type of diluents, and interfering ions, have been studied. It is shown to be a very effective extractant for titanium (IV) from perchloric acid medium, however, the time of extraction is very long (10 min). The extraction of titanium is independent of the initial metal ion concentration. Regarding competition among impurity metal ions, iron (III) seems to be the most competitive ion which could be avoided using fluoride ions as masking agent. The stripping of titanium was investigated using mixtures of 0.50 M NaF and 0.10 NaCl. The stripping procedure was very fast and the yield was 99.71%. The results of this investigation suggest that, it’s highly recommended to use the synthesized compound as extractant for titanium ions from its acidic media.
