The measurement technique detects the changes of bands in the UV range, which allows a direct correlation with the concentration. Thus, the measured absorbance signal allows a conclusion on the accumulation of fouling in the reactor and on changes in the conversion at the measurement location.eninfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/4.0/540article2023-04-05
