A combination of ultrasound and exfoliated graphite has been used to treat wastewater containing direct scarlet 4BS for colour removal and for the reduction of absorption at a wavelength of 242 nm. The results show that the ultrasound/exfoliated graphite process is effective in removing direct scarlet 4BS from aqueous solution. Furthermore, it can achieve better results than either exfoliated graphite or ultrasound alone.
