Supercritical water oxidation for the recovery of dysprosium ion from aqueous solutions
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 8
Abstract
Supercritical water oxidation (SCWO) is a new green technology to produce nanoparticles, destroy organic compounds and some inorganic compounds. In this research, supercritical water oxidation technique was used as an environmentally friendly technology for the recovery of dysprosium ions from aqueous solutions in the form of dysprosium oxide particles in a batch type reactor. The effect of three parameters includes temperature‚ reaction time and primary concentration of aqueous solution of dysprosium (III) nitrate in the constant pH of starting solution (5.2) on reaction efficiency was investigated using 23-1 fractional factorial design. By employing a regression analysis a model was proposed which can predict the percentage of reaction efficiency with acceptable confidence.
