摘要: OF THESIS MEMBRANE IMMOBILIZED REACTIVE Fe/Pd NANOPARTICLES: MODELING AND TCE DEGRADATION RESULTS Detoxification of chlorinated organic compound is an important and urgent issue in water remediation nowadays. Trichloroethylene (TCE), as a model this study, has been proved to be degraded effectively by bimetallic nanoparticles (NPs) solution phase. In NPs were synthesized poly (acrylic acid) (PAA) functionalized polyvinylidene fluoride (PVDF) microfiltration membranes. dechlorination with these was conducted under different pH values metal loadings study the role corrosion on reaction rates. One-dimensional mathematical pseudo first-order kinetic introduced discuss profile membrane system. Reduction pores affected several parameters including NP loading size, diffusivity, void volume fraction surface-area-based This result indicated that modification needed correct rate obtained from bulk order represent actual efficiency reduction reaction. addition, mainly occurred near NPs’ surface. Second part mechanism adsorption-desorption behavior could used high concentration.
