Radical Attack

The sonochemical degradation of sodium dodecylbenzene sulfonate (SDBS) has been studied over a wide concentration range spanning the critical micelle concentration (CMC) of the surfactant. The rate of degradation of SDBS increased linearly with increasing concentration below the CMC of SDBS. Above the CMC, the degradation rate continued to increase but at a much slower rate compared with that below the CMC. It was found that the increasing rate of degradation of SDBS correlated closely with the decrease in the air/water surface tension of the surfactant solutions. The results of this study strongly suggest that the initial step in the degradation process is OH• radical attack onto SDBS molecules adsorbed at the cavitation bubble/solution interface. The sonication of SDBS solutions for extended periods of time (ca. 12 h) led to the generation of gaseous hydrocarbon products, such as methane, ethane, ethylene, and acetylene. It is concluded that further radical attack occurs on the intermediates produced from the initial degradation step. This further degradation pathway is responsible for producing both water-soluble species, and volatile products that are pyrolyzed within the cavitation bubbles.

Elevated Salinity

The economic and effective application of surfactant enhanced remediation (SER) technology in a sediment-freshwater/saline water system was investigated by batch method using the combined effects of inorganic salt (sodium chloride, NaCl) and anionic surfactant (sodium dodecylbenzene sulfonate (SDBS)) on phenanthrene (PHE) removal via sorption by sediment. In all cases, PHE sorption followed a linear equation and partition as the main mechanism for PHE removal from aqueous solution. Separate addition of SDBS (2 mmol L−1) and NaCl (2–100 mmol L−1) moderately enhanced PHE removal, while with their combined addition the enhancement was substantial, and the removal efficiency achieved a peak of 92.8%. The combined effect expressed a synergy, and the sorption enhancement increased by factors of 2.7, 3.2 and 3.4 when compared with the sum of the separate entities at elevated salinity. This was because the sorbed SDBS, with increasing amount and a high packing conformation at elevated salinity, outcompeted aqueous SDBS for PHE partition. Moreover, a combination of 2 mmol L−1 SDBS and 2 mmol L−1 NaCl was optimal for PHE removal. Therefore, SER technology appears more effective for PHE removal in saline water than in freshwater, and preliminary water quality monitoring is essential for economic and efficient SER application.
