PME SPECIAL SEMINAR SERIES: Arlette Vega Gonzalez

Insights in understanding multi-phase Non-Thermal Plasma processes and their application as remediation techniques. 

Non-thermal Plasma processes (NTP) have been gaining attention for various applications, including environmental technologies. They can be used in various fields, such as indoor air treatment, NOx removal from engine exhaust, plasma-assisted combustion, VOC (volatile organic compound) decomposition, water treatment, etc. The Polyphasic Plasma Processes & Environment (3PE) team from the LSPM laboratory has been working on the experimental study and the modeling of plasma processes for more than 20 years. This dual approach has been applied to the study of processes coupling NTP and catalysis for the degradation of gaseous effluents. More recently, the group started working with electrical discharges in contact with aqueous solutions. This technique presents considerable potential, as an alternative for material’s synthesis as well as for wastewater depollution. Different applications of NTP, where the plasma is in interaction either with a gas phase or a liquid phase will be presented. More specifically, the use of NTP processes for acetaldehyde (a well-known COV) decomposition using the plasma-catalysis process, the synthesis of iron-based particles, and wastewater treatment for the elimination/decomposition of emergent pollutants-PFAS or heavy metals.

Arlette Vega Gonzalez holds the position of research engineer at the Processes and Materials Laboratory (LSPM), a CNRS (French National Research Center) laboratory located in the northern suburbs of Paris. She is the Principal Investigator of the Polyphasic Plasma Processes & Environment group, which conducts mostly experimental research on the use of plasma processes for environmental applications. In 1996 she obtained her PhD degree on the topic of “essential oils adsorption using supercritical fluids” from the Paris 13 University. After her PhD, she worked during more than ten years in the developing of supercritical processes for the crystallization of active compounds. In 2008 she completely changed her research subject, and to this day, she has been working with non-thermal plasma processes for depollution of gaseous or liquid effluents.
