| description | Degradation and detoxification efficiency of high concentrations of
commercially available reactive textile dye Reactive Black 5 solution (40,
80, 200, 500, 1000 mg L-1), were studied. Advanced oxidation processes in
water falling film based dielectric barrier discharge as a non-thermal plasma
reactor were used. For the first time, this reactor was used for the
treatment of high concentrations of organic pollutants such as reactive
textile dye Reactive Black 5 in water. Solution of the dye is treated by
plasma as thin water solution film that is constantly regenerated. Basically,
the reactor works as a continuous flow reactor and the electrical discharge
itself takes place at the gas-liquid interphase. The dye solution was
recirculated through the reactor with an applied energy density of 0-374 kJ
L-1. Decolorization efficiency (%) was monitored by UV-VIS spectrophotometric
technique. Samples were taken after every recirculation (~ 22 kJ L-1) and
decolorization percent was measured after 5 min and 24 h of plasma treatment.
The efficiency of degradation (i.e. mineralization) and possible degradation
products were also tracked by determination of the chemical oxygen demand
(COD) and by ion chromatography (IC). Initial toxicity and toxicity of
solutions after the treatment were studied with Artemia salina test
organisms. Efficiency of decolorization decreased with the increase of the
dye concentration. Complete decolorization, high mineralization and
non-toxicity of the solution (<10 %) were acomplished after plasma treatment
using energy density of 242 kJ L-1, while the initial concentrations of
Reactive Black 5 were 40 and 80 mg L-1. [Projekat Ministarstva nauke
