Synthesis of amine imprinted manganese ferrite and its application in the removal of free fatty acid from waste vegetable oil

The presence of free fatty acid (FFA) in waste vegetable oil (WVO) is undesired and must be removed. The present study synthesized amine imprinted manganese ferrite (MnFe2O4-DEA) via coprecipitation method and used it for the removal of FFA in WVO. Fourier transformed Infrared spectroscopy (FTIR) an...
