Biodegradability enhancement of textile wastewater by electron beam irradiation

Absolute cross section for loss of supercoiled topology induced by 10 eV electrons in highly uniform /DNA/1,3-diaminopropane films deposited on highly ordered pyrolitic graphite

“…The accuracy of simulations thus depends on data describing individual scattering events, e.g., those of SEs with condensed molecules. Electron-molecule cross sections are absolute quantities that describe these events and are thus essential for modelling radiation induced processes occurring in diverse fields including plasma processing, 4 water e-beam purification, 5 astro-chemistry, 6 human spaceflight, 7 and radiobiology. 8 In radiobiology, MC simulations can describe both the so-called direct effects of primary radiation and secondary species on DNA, as well as the indirect effects of OH • and other radicals produced in liquid water.…”

Treatment of opium alkaloid containing wastewater in sequencing batch reactor (SBR)—Effect of gamma irradiation

“…Barrera-Diaz et al (2003), who applied gamma irradiation on highly colored (3750 Pt-Co) industrial wastewater, stated that the radiation effects can be limited due to the colloidal matter that contributes to the high color present in the wastewater. On the other hand, Kim et al (2007) reported that biodegradability (BOD5/COD) of textile effluent increased by an electron beam radiation at 1.0 kGy.…”

“…Recently, chemical treatment methods, based on the generation of strong oxidizing hydroxyl radicals, known as advanced oxidation processes (AOPs), have been widely applied for pollutant degradation (Perez et al, 2002). Among the AOPs, application of radiation technology-including 60 Co-gamma irradiation and e-beam accelerator-in wastewater treatment is drawing considerable attention around the world (Bao et al, 2002;Duarte et al, 2002;Barrera-Diaz et al, 2003;Jo et al, 2006;Kim et al, 2007). Their application is based on interaction of reactive oxidizing and reducing species,which are formed by radiolysis of water, with organic pollutants in both primary (direct effects) and secondary ionizations (indirect effects) (Drzewicz et al, 2003).…”

Role of reactive intermediates in the radiolytic degradation of Acid Red 1 in aqueous solution

“…The researches in the field have led to laboratory demonstration of the applicability of technique, and to industrial pilot plant and full-scale established technologies for treating effluents of dying factories. The research with dye molecules is continued in the direction involving dye molecules with different structures in the investigations, clarifying the mechanism of the undergoing reactions, finding the most probable sites of radical attack on dye molecules and identifying the short-lived transients and stable intermediates of degradation (Kim et al, 2007;Wojná rovits and Taká cs, 2008;Emmi and Taká cs, 2008).…”
