Halogenated nonylphenol derivative

Fujita et al. [18] studied formation of halogenated (chlorinated and brominated) NPEOs and NPECs during wastewater treatment. Halogenated derivatives were found to be produced during the disinfection processes by chlorination accounting for up to 10% of total nonylphenolic compounds. They were found in 25 of 40 WWTPs with concentrations up to 6.5 xgL 1 in secondary effluent and 52.4 jig L-1 in final effluent. Of all halogenated compounds, BrNPECs (nEo = 1-2) were found to be the most abundant.

Petrovic et al. [35] reported the low ng/1 determination of nonylphenol, NPEC, and their halogenated derivatives in water and sludge from a drinking water treatment plant near Barcelona (Spain). Detection limits of 1-2 ng/1 in water and of 0.5-1.5 pg/kg in sludge were reported.
