“…Also, wastewater effluents are complex matrices that may introduce matrix effects that can be corrected through a laborious method known as standard addition. 65 For this reason, the method developed in this study is valuable because it can evaluate several DBP Environmental Science: Water Research & Technology Paper chemical classes with low detection limits in complex water matrixes. However, the varying chemical properties of different classes of DBPs and their unstable nature (i.e., volatile, light sensitive) resulted in a wide range of percent recoveries that were found to be similar to another multianalyte DBP method for drinking water.…”

“…Pyrene decomposes into volatile and semi-volatile oxygenated organic compounds by oxidation; the concentration of these organics is often very high and composition is complex [ 59 ]. Thus, inferring the degradation pathways and main products of pyrene is crucial for the treatment and application of water bodies.…”

In soil, polycyclic aromatic hydrocarbons (PAHs) are tightly bound to organic components, but surfactants can effectively transform them from a solid to a liquid phase. In this study, the biosurfactant rhamnolipid (RL) was selected as the eluent; shaking elution in a thermostatic oscillator improved the elution rate of pyrene, and the effects of RL concentration, temperature, and elution time on the elution effect were compared. After four repeated washings, the maximum elution rate was 75.6% at a rhamnolipid concentration of 20 g/L and a temperature of 45 °C. We found that 38 μm Zero-Valent Iron (ZVI) had a higher primary reaction rate (0.042 h−1), with a degradation rate of 94.5% when 3 g/L ZVI was added to 21 mM Na2S2O8 at 60 °C. Finally, electron paramagnetic resonance (EPR) detected DMPO-OH and DMPO-SO4 signals, which played a major role in the degradation of pyrene. Overall, these results show that the combination of rhamnolipid elution and persulfate oxidation system effectively remediated pyrene-contaminated soil and provides some implications for the combined remediation with biosurfactants and chemical oxidation.

“…In addition to these intermediates in the aqueous solution, some oxygenated organic compounds (O-VOCs) with lower boiling points were also detected by GC-MS. Due to their negative impact on the environment, various detection methods of O-VOCs have been developed, including static headspace, dynamic headspace, solid-phase extraction, etc. 33 A static headspace technique was used in this study. The SDS degradation products measured by GC-MS are presented in Table S3.…”

The UV/H 2 O 2 process was employed to purify cold-rolling emulsion wastewater (CREW). The degradation of CREW was mainly attributed to the combined UV/H 2 O 2 process and exhibited pseudo-firstorder reaction kinetics. The reaction parameters, including the H 2 O 2 dosage, initial pollutant concentration, initial pH, UV intensity, and inorganic anions, were found to influence the removal efficiency of chemical oxygen demand (COD) and reaction rates. In addition, the optimal experimental conditions were determined: H 2 O 2 dosage of 0.2 mol/L, initial pH of 9.13, and UV intensity of 4.0 mW/cm 2 . The final residual COD concentration decreased from 3573 mg O 2 /L to 67 mg O 2 /L, and the treated wastewater complies with the wastewater discharge standards in China (COD concentration of 80 mg O 2 /L) and can be discharged. Meanwhile, • OH was identified as the primary reactive radical in the process. Sodium dodecyl sulfonate (SDS) and hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine (BK) were selected as representative pollutants in CREW to explore the degradation mechanism. The products generated were identified by liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). Potential degradation pathways were proposed and discussed. The operational cost is 0.115 USD/L, which was calculated for the best conditions.
