Solvent extraction of aromatic compound from wastewater by biodiesel
Aromatic compound removal process from wastewater was developed with solvent extraction. This study concerned the new extraction solvent-biodiesel. Biodiesel as solvent has some special characteristics: it has a smaller solubility in water; it has a higher flash point; it is nontoxic; and it is biodegradable. In this work, the solute removal rate, COD removal rate and solvent recovery were studied. In addition, the multistage countercurrent extraction experiments were carried out. The results showed that the multistage extraction rates of aniline, nitrobenzene and phenol were greater than 98.67%. The recovery performance of biodiesel was better.
