Process of using a catalyst for photo-catalytic degradation of contaminant in water

摘要

This invention relates to the process of using a catalyst for the photo-catalytic degradation of methyl tertiary butyl ether (MTBE) in water. A Pd/Ce2O3—ZnO photo-catalyst is formed to react with MTBE dissolved in water sample and UV irradiated to reduce the MTBE concentration in the water sample. A 95-97% degradation of MTBE is observed using this process.

主权项

1. A process, comprising:
fitting a cooling jacket; adding a Pd/Ce2O3—ZnO photo-catalyst into deionized water containing MTBE and forming a solution; loading the solution onto a photochemical reactor and stirring continuously; collecting a sample from de-ionized water containing MTBE and designating as an initial concentration of MTBE (Co); saturating the sample by passing an oxygen gas using an inlet tube through the sample; exposing the sample from the saturating step to UV light; collecting the sample after exposing to UV light at a regular interval of time and estimating a reduction of an amount of MTBE in the sample using a gas chromatography.
