Investigation And Optimization Of Different Types Of Draw Solutes For Forward Osmosis Water Desalination
forward osmosis, superparamagnetic magnetic nanoparticle draw solute, mixed ligand complex, synthetic organic potassium salt, ionic liquid draw solution
This work has been carried out to prepare, characterize different types of draw solutes with high osmotic pressure and to study their performance as draw solutes in forward osmosis desalination. These draw solutes are of different types namely, Superparamagnetic organic caped magnetic nanoparticle, mixed ligand complex, synthetic organic potassium salt which can be also used as fertilizer and ionic liquid draw solution. The draw solutes were prepared and fully characterized in terms of composition, XRD, IR, TGA, Zeta potential analysis, TEM, VSM, Spectrophotometric analysis, Conductimetric analysis. Each draw solute was applied to forward osmosis water desalination against de-ionized water (as a feed solution) and against different concentration of NaCl solutions feed solutions and the optimum draw solutes were applied to desalinate the real sea water and well water.
