“…Therefore, a considerable amount of scientific studies on the degradation of PVA has been carried out. Most of these studies have focused on electrocoagulation (Chou et al 2010), biodegradation (Solaro et al 2000), adsorption (Behera et al 2008), the Fenton process (Kang et al 2002), photo-Fenton oxidation (Giroto et al 2006), chemical oxidation (Won et al 2001), and photocatalytic degradation (Hsu et al 2011). These methods have certain drawbacks, including long operating time and high capital costs.…”

This investigation evaluates the effectiveness of UV-365 nm/S 2 O 8 2-process in degrading polyvinyl alcohol in aqueous solutions. The effects of pH, Na 2 S 2 O 8 dosage, and temperature on the degradation efficiency of polyvinyl alcohol were studied. Under acidic conditions, the degradation efficiency of polyvinyl alcohol exceeded that under alkaline conditions. Additionally, a higher Na 2 S 2 O 8 dosage and a higher temperature were associated with a higher degradation efficiency of polyvinyl alcohol. The degradation rates of polyvinyl alcohol followed a pseudo-first-order kinetic model. Moreover, the observed degradation rate coefficient increased from 0.0078 to 0.4081 min -1 when the temperature was increased from 10 to 55°C. Also, the activation energy estimated using the observed degradation rate coefficients and the Arrhenius equation was 64 kJ/mol. At UV-365 nm, pH 3, an Na 2 S 2 O 8 dosage of 0.06 g/L, a temperature of 55°C, and an initial polyvinyl alcohol concentration of 20 mg/L, around 100 % of polyvinyl alcohol was degraded, indicating that UV-365 nm/S 2 O 8 2-process has great potential in degrading polyvinyl alcohol in aqueous solutions.

“…However, sludge generation and adsorbent regeneration are the principal weakness of these processes (Slokar and Majcen Le Marechal, 1998). The Fenton process that uses Fe 2+ to react with H 2 O 2 to generate OH with powerful oxidizing ability, one of the advanced oxidation processes (AOPs), has been proposed for the degradation of organic pollutants (Chen and Pignatello, 1997;Benitez et al, 2001;Huang et al, 2002), including some dye pollutants (Kang et al, 2002;Feng et al, 2003;Swaminathan et al, 2003).…”
