Pertraction of vanadium from aqueous solution using emulsion liquid membrane technique

Emulsion liquid membrane technique is from the new alternative methods that proposed for recovery and enriching the heavy and precious metals. Recovery of vanadium isimportant from environmental and economical view points. This paper has been investigated vanadium pertraction efficiency by ELM method. The effect of important parameterssuch as concentration of surfactant, organic phase to internal aqueous phase volume ratio, concentration of internal phase,emulsification speed and time of emulsification have been considered at constant temperature. The results showed anenriching ratio more than 10 within less than 1 hour. Vanadium extraction efficiency was more than 68%.
