摘要

Abstract

In this work

a novel catalyst of Fe

@SiO

@Yb

was prepared and the degradation of thymol in reverse osmosis concentrate using ozonation was explored. The operational parameters

such as ozone dosage (8-48 mg·min

-1

)

initial thymol concentration (20-100 mg·L

-1

)

initial pH value (3-11)

and catalyst Fe

@SiO

@Yb

dosage (0.2-1.0 g)

were studied focusing on the thymol degradation and COD removal. The results indicated that the increase in ozone dosage

initial pH value

and Fe

@SiO

@Yb

dosage accelerated the thymol degradation and COD removal

while the increase in initial thymol concentration hampered the effect of ozonation. A pathway of thymol degradation by catalytic ozonation was proposed based on the intermediates detected by gas chromatography-mass spectrometer and ion chromatography. This paper can provide basic data and technical alternative for pollutant re

moval from reverse osmosis concentrate by ozonation.
