[Analysis of Pollution Characteristics and Sources of Atmospheric VOCs in Ezhou City].

From March 2018 to February 2019, quantitative detection was made of 102 kinds of atmospheric volatile organic compounds (VOCs) using online gas chromatography in Ezhou City. We compared and analyzed the composition, seasonal variation, and diurnal variation of VOCs. Using maximum incremental reactivity (MIR), we estimated the ozone generation potential (OFP) of VOCs.

[FTIR study of adsorption of PCP on hematite surface].

The adsorption of pentachlorophenol on hematite was studied through adsorption experiments and FTIR analysis. The pH adsorption isotherms of pentachlorophenol onto hematite were obtained by the static state experiments. The largest adsorption quantity occurred at about pH 6.
