Wastewater and Diazepam (1 of 2) (IMAGE)
Caption
The globally-used anxiety drug Diazepam can now be removed from recycled water and wastewater, using low-cost titanium dioxide nanofibers, says Prof Vinod Gupta from the University of Johannesburg. First marketed as Valium, Diazepam is available in hundreds of brands. The drug is one of three benzodiapezines in the World Health Organisation list of essential medicines, but is also widely abused as an addictive prescription drug. In cities running out of water, removing pharmaceuticals from wastewater in a simple, low cost way is becoming a priority. This 3D image shows Diazepam's molecular structure.
