| dc.description | The decolorization of the Basic violet I (BVI) dye when interacted with a corona discharge is studied in the present work, taking in account two systems, batch and flux. The current and voltage were measured during the whole process in which a corona plasma was generated, with an applied power of 51.9 and 167.72 W where the transport gas was air. A batch reactor and a flow reactor were used, where 500 and 5000 mL of samples were treated, respectively. Optical emission spectra (OES) were measured where the oxidizing species ・OH were at wavelengths of 307.597 and 310.148 nm, associated with the A2Σ+ − X2Π transition. The absorption spectra for the batch system showed a discoloration of 85.7% in the first 10 min, while in the flow system, the absorption was 93.9% at the same time and 4.5% at the same time by conventional heating. Characteristics of the final sample included an acidic solution with an electrical conductivity of 449.20 } 55.44 and 313.6 } 39.58 μS/cm, a dissolved oxygen concentration of 7.74 } 0.2 and 6.37 } 0.23 mg/L, an absorbance of 0.04 } 0.01 and 0.03 } 0.01 au, with turbidity measuring 1.22 } 1.59 and 10.34 } 4.96 NTU, and an energy cost of 1.1 × 10−1 and 6.3 × 10−1 g/kWh in the batch and continuous flow systems, respectively. The interaction of the corona plasma with water promoted the production of reactive species, resulting in the discoloration of the Basic Violet I dye. | es_MX |
