“…The H 2 O 2 produced in the water was quantified using the formation of pertitanic acid, which was generated from the reaction of titaniumsulphate and H 2 O 2 . Then a UV-Vis spectrophotometer was used at the wavelength of 410 nm (detection limit is 1.5×10 -4 M) to determine the absorbance of pertitanic acid (Marotta, 2012).…”

“…), shockwave, ultraviolet light and electrohydraulic cavitation may degrade the pollutant in waste water or decomposes the pollutant into other compound [102].In liquid and gas plasma can be created either directly in the liquid, or in the gas above the liquid, or, in case of hybrid rectors, both in liquid and in gas. The more efficient way which requires less energy for waste water treatment can be done by diffusing gaseous phase species into liquid [103] .Recent investigations of Non thermal plasma on oxidation of products in water phenols [104] organic dyes [105], degradation of pharmaceutical compounds [106], pesticides [107] and also mineralization of pollutants by using several catalysts are also reviewed extensively [103]. Extensive research for commercial design of non-thermal plasma waste water treatment equipment should involve in theoretical aspects of diversified fields of Engineering, Electronics and Applied Sciences.…”

Cold Plasma: A novel Non-Thermal Technology for Food Processing

In the past cold plasma is used for sterilization of sensitive materials and now it is extended to food industries as a novel technology. For years cold plasma processing has been viewed as useful for microbial inactivation while maintaining quality of fresh produce. However, this process is not effective for in vitro model food systems for inactivation of microbes or enzymes which are present in intact tissues, as it is a surface phenomenon. Cold plasma technology is also used to inactivate endogenous enzymes which are responsible for browning reactions particularly polyphenoloxidase and peroxidases. Several research investigations showed a reduced growth of microorganism via different mode of actions by etching phenomenon, cell disruption by electrophoration etc. Plasma technology is considered as modern non conventional technique which is used for the preparation of modified starches, altering its physical and chemical properties. Overall application of cold plasma for microbial destruction on different food substrates like fruits, meat products, cheese etc. was discussed. Besides this, it is also used to alter the germination rate of seeds. It is an eco-friendly process which is used in the preservation of food and other potential applications as an alternative to common techniques.

“…The two systems were compared based on the reactive species produced in the liquid phase and on their performance in the degradation of a model organic pollutant (phenol) in water. Due to its wide diffusion as water contaminant and its well‐known reactivity and products in reactions with ROS, phenol is the most commonly used model for testing and comparing AOPs . Specifically, for the comparative evaluation of the sources developed and tested in this study the following data were considered: energy efficiency, by‐products, and extent of mineralization of organic carbon into CO 2 .…”

A reactor with two interchangeable plasma sources was developed and tested in water decontamination experiments using phenol as model organic pollutant. The two configurations were characterized and compared by determining the reactive species produced in the aqueous phase (concentration of ozone and of hydrogen peroxide as a function of input energy and rate of OH radical production) and the efficiency in phenol degradation. The streamer discharge performed significantly better than the dielectric barrier discharge: the rate of OH radicals production was ten times faster and the efficiency of phenol degradation, as measured by the G50 parameter, was more than twice as large. Moreover, the streamer discharge induced process was kinetically faster and achieved better mineralization yields in shorter times.
