Efficient and sustainable filtering process of salt and metal ions from water discovered by researchers




The blended research study of Monash University, CSIRO, and the University of Texas at Austin provides a breakthrough discovery of a new solution for people to access clean and safe water for drinking.
MOFs (Metal-organic frameworks) are a fascinating next generation component that has a huge surface area internally as compared to any known element. The crystals are similar to sponges and they can be utilized to capture, collect, and let go of chemical compounds, like salt and ions found in the sea water.
The team of researchers found out that the MOF membranes can copy the filter functionality or ion selectivity of the cell membranes which are organic. The research team includes the Monash University Faculty of Engineering in Melbourne, Australia, Dr. Huacheng Zhang, Professor Huanting Wang, Associate Professor Zhe Liu, and their team; CSIRO’s Dr. Anita Hill, and the University of Texas at Austin’s McKetta Department of Chemical Engineering Professor Benny Freeman.


Additional development shows that the membranes have compelling likelihood to accomplish dual functions of clearing away salts from seawater and dividing metal ions in an effective and cost efficient way. This provides a radical new technological method for the water and mining business.
The 2003 Nobel Prize in Chemistry that was given to Roderick Mackinnon and Peter Agre talks about the current processes of water treatment, reverse osmosis and the limitations of ion transport.
Membrane processes in the mining industry are enhanced to lessen the water pollution and to reclaim significant metals.
Professor Wang from Monash University stated that their research can be utilized to address the issues regarding desalination of water, as this new research opens doors for possible salt ions removal in energy efficient and environmentally viable method. He mentioned that this research will be further continued to see how lithium ions can be advantageous in extracting lithium ions from the seawater.
Dr. Hill from CSIRO stated that the MOFs growing science have the potential to better filtration for sustainable water.
Professor Freeman of the University of Texas in Austin said that the separation concepts of materials can possible convert waste stream of water into a resource reclaiming favorable circumstance.
The research was sponsored by the Commonwealth Scientific and Industrial Research Organization (CSIRO) for the Australian-American Fulbright Commission for the US Fulbright Distinguished Chair in Science, Technology and Innovation.
