Abstract
Triton X-114 based cloud point extraction has been demonstrated to be an advantageous approach for the recovery of nanosized copper oxide (NCO) from water. The removal of NCO was influenced by the concentrations of TX-114 and salt, incubation temperature and time, as well as solution pH. With the addition of 0.3% (w/v) Triton X-114, over 88% of the spiked NCO was removed from wastewater after incubation at 35°C for 2 h and centrifugation, whereas over 85% of NCO was recovered after incubation at 28°C for 20 h by gravity phase separation, which is economical and energy-saving. This study suggests that the cloud point extraction technique has great potential in removal of nanomaterials from wastewater.
