Mathematical modelling of MS2 virus inactivation by Al/Fe-PILC-activated catalytic wet peroxide oxidation (CWPO).

摘要: Catalytic wet peroxide oxidation (CWPO) is a novel, alternative technology to conventional disinfection methods that are widely used control microbial parameters in drinking water. To assess its effectiveness, new studies revealing the kinetics of MS2 coliphage inactivation by CWPO required. This investigation therefore aimed perform mathematical modelling through activated an Al/Fe-pillared clay catalyst (Al/Fe-PILC) presence synthetic surrogate dissolved natural organic matter. The constant was obtained from two different statistical approaches, and experimental data were better fitted pseudo-first-order Chick-Watson model which rate constant. For this model, maximum k = 0.1648 min-1, achieved MS2-3 catalytic test using initial mass ratio active iron (Feact) 1.2 mg H2O2/mg Feact. estimate due reactive oxygen species (ROS), we supposed depends on both ROS In case, kr = 2.4 × 10-9 min-1 (using 1.17 mg H2O2/mg Feact), MS2-10 trial; cases led conclusion optimal Fe Al/Fe-PILC close These kinetic showed rapid takes place very early reaction, followed slow during remaining period recorded reaction time. research revealed strong potential improve microbiological water high performance heterogeneous Fenton displayed sites incorporated Al/Fe-PILCs.
