Extractive Separation and Determination of Zinc, Cadmium, and Mercury Using Tributyl Phosphine Oxide as Extractant in Salicylate Medium
Abstract: The Present study describes extractive separation of Zinc, Cadmium and Mercury with Tri-n-butylphosphine oxide (TBPO) as an extractant. There are various methods for extraction of Zn(II), Cd(II) and Hg(II). However, they suffer from longer extraction period, incomplete extraction and use of salting out agents. The optimum extraction conditions for Zinc, Cadmium and Mercury are evaluated by changing concentration of extractant, sodium salicylate, pH, diluents and shaking period. The extraction takes place by solvation mechanism, where metal salicylate is solvated by TBPO rendering it hydrophobic and facilitating extraction into the organic phase. The method is simple, rapid and selective. It facilitates mutual separation and estimation of Zinc, Cadmium and Mercury in thirty minutes. It is also applied to separation and estimation of Zn (II), Cd(II) and Hg(II) from various industrial, Pharmaceutical and Environmental samples.
