Remediation of phenanthrene contaminated soil by ferrous oxalate and its phytotoxicity evaluation.

Phenanthrene contaminated soil was remediated by the photochemical process of ferrous oxalate. Without using HO and adjusting soil pH, phenanthrene in contaminated soil was degraded effectively by the ferrous oxalate under visible light irradiation. Ferrous oxalate possesses excellent visible light absorption ability which benefits the degradation of phenanthrene in soil under visible light irradiation.

Treatment of simulated electroplating wastewater containing Ni(II)-EDTA by Fenton oxidation combined with recycled ferrite process under ambient temperature.

Developing low cost and efficient method for the treatment of electroplating wastewater containing heavy metals complexed with chelating agent has attracted increasing attention in industrial wastewater treatment. This study involved a system combining Fenton oxidation (FO) and recycled ferrite (RF) process for treating synthetic solution containing Ni(II)-EDTA at ambient temperature. In this system, the FO reaction can produce hydroxyl radicals with high redox potential to decomplex the metal-organic complexes and degrade the organics, thereby enhancing the removal efficiency of heavy metals.

Remediation of phenanthrene contaminated soil by g-CN/FeO composites and its phytotoxicity evaluation.

This work is a premier demonstrating the technical feasibility of remediation of PAHs-contaminated soil by g-CN/FeO. g-CN/FeO has been synthesized by typical two steps involved the synthesis of g-CN and the subsequent in situ co-precipitation of FeO nanoparticles. g-CN/FeO exhibits excellent visible-light-driven photocatalytic activity for the degradation of phenanthrene in soil at circumneutral pH.

In situ investigation of Geobacillus stearothermophilus spore germination and inactivation mechanisms under moderate high pressure.

Bacterial spores are a major concern for food safety due to their high resistance to conventional preservation hurdles. Innovative hurdles can trigger bacterial spore germination or inactivate them. In this work, Geobacillus stearothermophilus spore high pressure (HP) germination and inactivation mechanisms were investigated by in situ infrared spectroscopy (FT-IR) and fluorometry.
