Congratulations to Zou Zhenping on his paper officially published by "Plasma Processes and Polymers" and selected as the cover article of the journal, with the title "Detection of long-lived species in plasma-activated water,based on digital colorimetry".
Nowadays, low-temperature plasma technology has broad development prospects in various fields such as food safety and green agriculture. In response to the irregular shape of the treatment object or the size of the plasma source itself, water is often used as the intermediate medium, and a large area and uniform treatment can be provided after the plasma activation. The regulation of plasma activated water is mainly affected by liquid phase long-life particles: NO2-、H2O2, etc. Correspondingly, plasma liquid phase diagnosis has attracted wide attention. Traditional methods of liquid phase component detection include electrochemical method, spectroscopy and chromatography, and these methods have harsh conditions to use, complex operation and expensive measurement costs, which are not applicable in practical applications. In this paper, we study a detection method based on visible light image analysis, and compared with the results of traditional UV-Vis spectrophotometer under the same conditions, it is found that the detection effect of this method is equivalent to that of spectral method. At the same time, it has obvious advantages in portability, operability, applicability and measurement costs.
