It is very difficult to extract heavy metals, hydrocarbons and radioactive metals from industrial wastewater. Researchers usually focus on cleaning and purifying wastewater to prevent these pollutants from entering the environment and damaging ecosystems. However, a research team of the Missouri Department of science and technology has designed a method that can not only remove heavy metals from wastewater, but also promote the recovery of chemicals used and the reuse of extracted metals.
Dr. Muthana al Dahan, distinguished professor of chemical and biochemical engineering at Missouri University of technology and kusay Jafar obadi University, has developed a system that collects pollutants more than 10 times more efficiently than existing methods. The method patent has entered the final approval stage. The patent adds nanoparticles and ionic liquids to enhance the emulsion liquid membrane (ELM) extraction process. The technology combines the extraction and stripping of water-based pollutants into one stage.
This is the first time that nanoparticles and ionic liquids are combined to improve the extraction and recovery of heavy metals and hydrocarbons in a shorter time, or remove them from wastewater and water. Strengthening the separation of heavy metals can have a wide range of commercial applications. This approach is more effective and cost-effective, and may also protect the entire regional ecosystem from harmful chemicals.
Heavy metals and hydrocarbons are commonly found in runoff from pesticide, petroleum, energy and petrochemical industries and mining industries. When released into the environment, these compounds will accumulate in the food chain and continue to exist in nature, which may bring health problems to animals and plants.
In the extraction process, magnetic nanoparticles are used. Magnetic nanoparticles can be recycled and reused, which is of course more economical for industrial processes.
The current standard elm process expands and breaks during metal extraction. The stability of the separation process can be improved by adding a combination of nanoparticles and ionic liquids.
This stability is necessary for effective transformation on an industrial scale. By using this combination of nanoparticles and ionic liquids to enhance the separation process and improve the stability of elm, the process can be transformed from batch to continuous work and applied to large-scale commercial and industrial applications. Effective water purification and potential reuse of removed pollutants, especially heavy metals, can also promote new research trends in the field of chemical engineering.
