Degradation of sodium dodecyl sulphate in water using solar driven Fenton-like advanced oxidation processes

Cobalt-catalyzed sulfate radical-based advanced oxidation: A review on heterogeneous catalysts and applications

“…Solar driven Co/PMS process seems to be an applicable energy-saving technique[222,223]. Besides UV and Vis light, the range of infrared (IR) light in the sunlight can be utilized to elevate the temperature of the reaction system, so as to facilitate the catalytic reactions.Fig.…”

Mineralisation of Surfactants Using Ultrasound and the Advanced Fenton Process

“…Advanced oxidation processes have been investigated previously for surfactant wastewater treatment using Fenton oxidation (Lin et al 1999;Bandala et al 2008); electrochemical oxidation (Gu et al 2006), ozone and/or UV irradiation (Amat et al 2007) and Beltran and co-workers (2000) have also reported the kinetics of decomposition of DBS with ozone, but most of these studies have concentrated on the kinetics of removal of the surfactant rather than the decrease in total organic carbon.…”

“…Several authors report surfactant remediation experiments using several oxidising agents (MendezDiaz et al 2009) and AOPs such as photocatalysis supported by TiO 2 (Hidaka et al 1995;Ohtaki et al 2000;Zhang et al 2003;Vohra and Tanaka 2003;Zhang et al 2004;Horvath et al 2005), ultrasound (US; Manousaki et al 2004;Yim et al 2002;Yang et al 2005) and Fenton or Fenton-like processes (Lin et al 1999;Bandala et al 2008;Amat et al 2004), and most of these achieve good remediation in short reaction times (a few hours instead of days as happens using conventional wastewater treatment with activated sludge). The classical Fenton oxidation process (Fenton 1894;Haber and Weiss 1934;Barb et al 1949Barb et al , 1951a utilises the reaction of aqueous iron (II) salt with hydrogen peroxide to generate hydroxyl radicals, which are then used to carry out chemical oxidation or to degrade recalcitrant organic pollutants in wastewater treatment Eq.…”

Decontamination of soil washing wastewater using solar driven advanced oxidation processes

“…In a precedent work [41] we have studied the actual oxidation of the surfactant used for soil washing (SDS) and found the best conditions applicable to its oxidation. In this work we used those previously identified conditions for SDS oxidation to real wastewater.…”

“…In a recent work, we reported the application of photoassisted Fenton-like processes for surfactant degradation [41]. Few studies dealing with Fenton and photo-Fenton process for the pretreatment of wastewater from soil washing process had been reported [36,37] and, to our knowledge, no reports dealing with the treatment of soil washing wastewater containing both surfactants and petroleum hydrocarbons using solar driven cobalt/PMS/UV process have been published.…”
