Abstract

Background and purpose

Surfactant-assisted soil washing and photocatalysis are well-known remediation processes of environmental concern. The application of photocatalysis to treat soil washing extracts containing 4-methylphenol, 4-ethylphenol and 4–tert-butylphenol in the presence of nonionic (C12E8 and C12E23) and anionic (SDS) surfactants and some of their binary mixtures was investigated in this work by studying the pollutants degradation in the presence of TiO2 dispersions irradiated with simulated solar light.

Materials and methods

Clean soil samples were spiked with the investigated alkylphenols. Aqueous solutions of the chosen surfactants were placed in contact for some hours with the spiked soil samples in a rotatory mixer. The pollutants recoveries were evaluated via HPLC analysis. Photocatalytic experiments were performed in solarbox on aqueous solutions and on aqueous surfactant solutions containing the pollutants.

Results

The pollutants removal from the soil was proven effective using the examined surfactant solutions. The photocatalytic treatment of the wastes was faster using Brij 35, but also SDS and C12E8–SDS mixtures can be applied. After 2–5 h the complete pollutants abatement was obtained, depending on the surfactant chosen and on the amount of TiO2 employed. On the contrary, the treatment of wastes containing C12E8 was an extremely slow process.

Conclusions

The photocatalytic approach can be applied to remove the examined aromatic pollutants from the washing wastes, confirming the viable coupling between this advanced oxidation method and the surfactant-based soil remediation treatments. Surfactant adsorption onto TiO2 and micelles concentration play a dominant role.
