The Study of Effective Parameter on Metals Extraction (Co, Hg, U and Cu) with Supercritical Fluid

In recent years a lot of researches have been done on extraction by supercritical fluids. In supercritical fluid extraction, several factors affect on extraction efficiency. Although, in this paper some of effective parameters on metals SFE have been investigated, but these factors have similar behavior in other applications of SFE. In this paper the effect of different ligand, their synergistic effects, modifier (SFE modifier), water and the volume of supercritical fluid (or in other words, supercritical fluid flow rate) have been investigated.
