Water Purification Gets Better With New Green Tech

The new research published in ACS Applied Nano Materials shows a quick and sustainable way of degrading organic dyes from wastewater in real time using the Vortex Fluidic Device (VFD).

Led by Dr. Xuan Luo from Flinders University’s College of Science and Engineering, the study utilizes three VFD applications, namely material fabrication, reactor coating, and material ‘banding’.

The VFD generates the active catalytic material within 30 minutes. It is composed of magnetite nanoparticles and copper phosphate nanoflower composites. It increases degradation efficiency by five times, enabling the device to degrade four different organic dyes in real time.

The team also chemically modified the VFD tube reactor with a thin silica-activated carbon xerogel coating to enhance the degradation. The coating, which works synergistically with the catalytic nanoflowers, boosts the degradation efficiency, enabling the VFD to degrade organic dyes by about 30 times compared to using batch processing.

The VFD was invented by Prof. Colin Raston, also from Flinders University, in 2013 and is known for various applications, including controlling chemical reactivity, enabling rapid modifications in self-organized systems, and synthesizing esters, amides, and ureas, among others.
