Microwave-Induced In-Liquid Plasma for Chemical and Environmental Applications: Investigation of Wastewater Treatment Contaminated by Microplastics and Toxic Metal Ions
Summary
Researchers used a microwave-induced in-liquid plasma device to degrade microplastics and toxic metal ions in contaminated water, demonstrating that polyethylene particles were degraded under continuous circulation treatment and that the method outperformed conventional batch treatments when assessed using rhodamine-B dye as a model contaminant.
This study utilized a microwave-induced in-liquid plasma (MILP) device to treat water contaminated with microplastics (MPs) and metal ions. The performance of the device was initially assessed using a rhodamine-B (RhB) aqueous dye solution in a circulation-type reactor, yielding a greater degradation efficiency compared to conventional batch treatments. Polyethylene (PE) particles (diameter, 20 μm; average molecular weight, 1.8 million) served as a model for MPs to evaluate their disposal and degradation under continuous circulation treatment. A plasma-induced polymer gel synthesis method was employed to remove metal ions, achieving over 80% removal of copper, tin, lead, and mercury within 5 minutes. These findings highlight the significant potential of MILP technology for innovative advanced water treatment applications.

Environmental aspects of restoring the environment: nanotechnology for removing micro and nanoplastics from water
Researchers developed a plasma chemical water purification method that combines modified humic substances with high-voltage electrical discharge to aggregate and magnetically remove micro- and nanoplastics from contaminated water. Tested on wastewater from a printing facility, the method outperformed conventional sorption or plasma treatment alone and showed promise for simultaneously removing plastics, heavy metals, and organic pollutants. This offers a potentially scalable technology for treating industrial wastewater sources that are currently releasing nanoplastics to the environment.
