Research on decoloration of dye wastewater by combination of pulsed discharge plasma and TiO2 nanoparticles

Nanomaterials for environmental burden reduction, waste treatment, and nonpoint source pollution control: a review

“…Acid Orange 7 (one of the widely used dyes) in wastewater can be degraded with TiO 2 nanoparticles [79]. Nanostructure Sn 4+ -doped TiO 2 -based double layer thin films have a very high photocatalytic performance for degradation of Malachite Green dye in solution [80].…”

Removal of acid orange 7 by guava seed carbon: A four parameter optimization study

“…Oxidative radiolysis [9][10][11][12] and the photo-Fenton process [13][14][15] have proven to be a good approach for the degradation of AO7. The efficacy of titania [16][17][18][19][20][21][22][23][24][25][26], SnO 2 [17] and ZnO [27], and a number of irradiation conditions have been also studied for the decolorization of this monoazo dye. Due its commercial significance, electro-photochemical [28] and electrochemical [29,30] studies of AO7 and its metabolites [31] can be found in the literature.…”

Plasma Technology: A New Remediation for Water Purification with or without Nanoparticles

“…Th e results obtained further confi rm that streamer produced by pulsed discharge plasma induced the photocatalysis of TiO 2 and there has been an optimal TiO 2 amount in the pulsed discharge system for achieving a higher decoloration effi ciency of AO7. Th e synergistic decoloration effi ciency of AO7 has been found to be higher in the case of higher input power [59]. Recently, isolated nanoparticles of TiO 2 were deposited over substrates providing larger surface area for the photocatalytic process.…”
