英文摘要This study focused on the performance of FeOx/OMS-2 nanorods via PMS activation to degradation carbazole (CBZ) and alkylated CBZs, as well as the possibility of application in oilfield produced water (OPW) with high concentration of co-existing anion/cation. Under the optimized reaction conditions with 0.25 g/L FeOx/OMS-2, 0.5 mM PMS, 30 C and 150 min, the removal rate and mineralization rate of CBZ at 20 mg/L could be reached 97.5 % (with the reaction rate constant of 0.0344 min(- 1)) and 50.3 %, respectively. The FeOx/OMS-2/PMS system could efficiently degrade CBZ at a wide pH range (pH = 3-9) and showed an excellent anti-interference ability to various anions and cations (Cl , SO42- , HCO3-, NO3- , Na+, K+, Ca2+, Mg2+, Ba2+ and Sr2+), especially the concentration of NaCl up to 10 g/L. Moreover, it was found that >84.7 % CBZ removal efficiency was reached in real water samples including the actual OPW. The removal rates of various alkylated CBZs were explored and the degradation rate decreased with the increase of methyl number. FeOx/OMS-2 showed an acceptable recyclability and stability, attained a removal efficiency of 63.2 % in the third cycle. Finally, scavenging tests and electron paramagnetic resonance (EPR) showed that (1)O(2 )was the main reactive oxygen species in this system. Accordingly, FeOx/OMS-2/PMS system with high performance was an efficient and promising process for the removal of CBZ in various water treatments.
