A research team at the University of Bath’s Centre for Sustainable Chemical Technologies, and the Water Innovation and Research Centre (WIRC), led by Simon Lewis, has developed a simple colour-changing test that detects high levels of fluoride quickly and selectively. The test changes from purple to blue when the levels of fluoride in the water are too high. Whilst the test is at the proof of concept stage, the team aims to develop it into a disposable test strip that is low cost and easy to use by anyone.
The Bath researchers are partnering with the Nasio Trust, a charity that works to protect and support vulnerable children in East Africa, to develop their system for ease of use in the field.
The team is now looking for additional partners to take the technology forward and help develop the test. They are also working towards adapting the technology to other types of notorious water contaminants of global concern, including mercury, lead and cadmium.
The core project team consists of Carlos López-Alled, Simon Lewis, Jannis Wenk and Tony James.
