Stopped-Flow Analysis in Water Treatment
Water has an extremely large number of uses but it is often not in a suitable condition for these uses when extracted from the environment. Water must be treated to remove contaminants that may, for example, be harmful to human health or industrial processes. Wastewater must also be treated to allow it to be recycled, or safely retuned to the environment. Free chlorine is the most widely used chemical disinfectant in the world, and stopped-flow spectroscopy allows for immediate and continuous observation of chlorination reactions, which are extremely fast. Being able to predict the efficiency of the removal of micropollutants and optimal conditions for doing so has the potential to change the water treatment industry in the future.
