The dye degradation efficacy of the cold plasma pencil jet is presented in the present investigation. Air plasma is produced in the cylindrical coaxial dielectric barrier discharge configuration. Electrical characterization of plasma is performed and the plasma species are identified using optical emission spectroscopy. For the dye degradation study using air plasma, six different types of dyes (erythrosine, metanil yellow, sudan I, crystal violet, rhodamine B, and Indigo) are chosen. The degradation of dyes is analyzed using UV visible spectroscopy, total organic carbon, and chemical oxygen demand. The results showed complete degradation of all the dyes in UV visible analysis with minimum time for indigo (3 minutes) and maximum time for erythrosine (45 minutes). Moreover, erythrosine (k = 1.08 mg L-1 min-1) and sudan I (k= 3.46 mg L-1 min-1) follows zero-order degradation kinetic and metanil yellow (k = 0.094 min-1), crystal violet (k = 0.25 min-1), rhodamine B (k = 0.17 min-1), Indigo (k = 0.81 min-1) follows first-order degradation kinetics. Also, substantial enhancement in mineralization and reduction in chemical oxygen demand of all the dyes occurs after plasma treatment. The toxicity of plasma degraded dye solution toward freshwater algae species (Chlorella Sorokiniana and Chlorella Pyrenoidosa) are significantly low compared to virgin dyes solutions. The study reveals that pencil plasma jet substantially degrade dyes as well as converts the dyes solutions non-toxic.

Large-scale production and application of synthetic dyes have become a matter of concern as it is a major factor responsible for environmental pollution. Most dyeing effluents are discharged into water bodies and lands without being treated, which ultimately pollutes the groundwater making it unfit for consumption. The present study explains the degradation of one of such synthetic dyes Methylene blue (MB), using non-thermal Microplasma treatment. The aqueous solution of MB was treated with an array of air microplasma discharge at atmospheric pressure. Different concentrations (10 ppm, 20 ppm) of MB solution were treated for various treatment time and chemical parameters like pH, electrical conductivity, total dissolved solids and salinity was measured. The degradation percentage reached 100% in 15 min of treatment for 10 ppm MB solution, and 20 min of treatment for 20 ppm MB solution indicated by the color change from blue to a clear solution. The reactive oxygen species (ROS) and reactive nitrogen species (RNS) formed during the microplasma treatment are responsible for MB degradation. Same volume of MB solution was irradiated by direct sunlight for photodegradation and was found to degrade the solution of 10 ppm by 96% and 20 ppm by 93% in 10 hours of treatment. Experimental results indicated that microplasma treatment was effective for dye degradation, without the need for pretreatment process or chemicals.

“…Recently, thermally nonequilibrium plasma jet treatment has gained significant consideration to degrade the contaminants in effluents without the need for external oxidants, adjustment of pH, and increase of temperature (Hijosa‐Valsero et al, 2013). The nonequilibrium plasma jet is generated by either applying an AC or DC electric field that causes the formation of various reactive species such as hydroxyl radical (OH • ), ozone (O 3 ), atomic oxygen (O), and hydrogen peroxide (H 2 O 2 ) at air–liquid interface via electron impact phenomena as well as UV radiation, shock wave which could facilitate degradation of various organic toxic components (Meiyazhagan et al, 2020). Various researchers have reported the degradation of various pollutants such as dyes and pharmaceutical drugs in wastewater using different plasma jets as depicted in Table 1 (Ghezzar et al, 2007; He et al, 2014; Hijosa‐Valsero et al, 2013; Hu et al, 2019; Magureanu et al, 2013; Reddy et al, 2014a; Zeng et al, 2015).…”

Degradation of residuals of chemical compounds after use has attracted the attention of environmental scientists. In this work, the degradation of such a toxic biocide compound of isothiazolin-3-one from an aqueous solution using a novel multi-pin thermally nonequilibrium atmospheric pressure plasma reactor is reported. This investigation examined the impacts of different operating conditions on the decomposition of isothiazolin-3-one. Subsequently, the reactive excited plasma species formed and participated during the degradation processes were examined by optical emission spectrometer (OES), chemical dosimetry using terephthalic acid (TA), and spectroscopic determination involving potassium titanium (IV) oxalate. The efficiency of degradation of the plasma-treated isothiazolin-3-one from an aqueous solution was examined by UV-Vis spectrometry. The mineralization of isothiazolin-3-one was further examined by high-performance liquid chromatography (HPLC), determining conductivity, total organic carbon (TOC), and pH of the isothiazolin-3-one aqueous solution. Finally, nontoxicity of the plasma-treated isothiazolin-3-one solution was investigated by seed sprouting and germination tests using Vigna radiata L. Wildzek (Mung bean). The experimental results exhibit that a higher degradation percentage of 96.01% was attained for the isothiazolin-3-one treated at a longer treatment time and higher potential of 25 min and 31 kV, respectively. This may be attributed to the formation of various reactive oxygen and nitrogen species (RONS) as confirmed by OES and other spectroscopic analyses. The value of pH and TOC is found to be decreased, whereas the value of electrical conductivity of the isothiazolin-3-one aqueous solution is increased linearly with an increase in treatment time and applied voltage. This indicates the degradation of isothiazolin-3-one molecules and the formation of various ionic species in the solution. The toxicity investigation reveals that the plasma-treated isothiazolin-3-one aqueous solution is nontoxic in nature and useful for sprouting and germination of the Mung bean seeds compared with the untreated one. Overall, it can be concluded that the plasma-assisted process is ideally needed in various food, pharmaceutical, and textile industries as a highly efficient treatment of wastewater.
