Extraction of resin from cashew nut sludge an Agro-industrial wastes

Abstract

In thiswork, the extraction of resin from the cashew nut sludge (agro-Industrial waste) was done using three different solvents namely methanol, propanol and diethyl ether. Among the three solvents propanol shows the better results for extraction of resin and it was further confirmed with FTIR, TGA-DTA and DSC. The FT-IR (Fourier Transform Infra Red Spectroscopic analysis was used to explore the structural changes of the extracted resin using propanol. The maximum peak obtained using propanol as a solvent for the extraction of resin was 14-16 min intensity. All the experimental study throughout the present study indicated that the obtained resin has wide application on waste water treatment. In future, it can be used as a cheap substitute instead of commercial resin for a better environment.
