Extraction and Separation Study of Mo(VI) and W(VI) Using Organophosphorous Extractant

Full Text PDF

Abstract:

Organophosphorous extractant, Cyanex-923, has been used for the extraction and separation of Mo(VI) and W(VI) is described. The extraction of the metal ions is studied as the function of several parameters such as effect of pH, effect of reagent concentration, stripping agents, diluents study and effect of diverse ion. It was observed that Cyanex-923 extracts Mo(VI) at pH 2.5-4.5 while W(VI) was extracted at pH 0.5-1.5. The extracted Mo(VI) was stripped back using 0.1M NaOH, while W(VI) was stripped back using 1.0 M (NH4)2CO3. The stoichiometry of the extracted species of Mo(VI) and W(VI) was determined on the basis of slope analysis method. Based on the results sequential methods of separation of both the metals were developed.
