Two-photon spectroscopy of the biphenyl chromophore. The electronic excited states of biphenyl and fluorene below 50000 cm-1 [PDF]

, 1985
The two-photon excitation spectra of biphenyl and fluorene in dil. soln. were measured up to 50,000 cm-1. Both spectra exhibit a medium intense band system in the range 32,000-42,000 cm-1, and a strong band above 45,000 cm-1. The lowest frequency feature

Insight into the degradation mechanism of fluorene by ferrous/humic acid activated persulfate: Free radical reactions, functional group verification and degradation pathway

Frontiers in Environmental Science, 2022
This study evaluated the performance of humic acid (HA)/ferrous ion (Fe (II)) activating persulfate (PS) for fluorene (FLU) degradation. Results showed that HA/Fe(II)/PS system exhibited the best performance for PS activation to eliminate FLU.
