Summary: The study compared the degradation performances of chlorobenzene using different oxidants activated with ferrous iron. The results showed that increasing the dosage of oxidants or Fe(II) improved the removal rate of chlorobenzene. Optimal molar ratios were determined for each system, with pH conditions significantly affecting the degradation performance. Hydroxyl radicals and singlet oxygen were detected, and the pathways of chlorobenzene degradation were proposed, highlighting the innovative role of singlet oxygen in the mechanism. Additionally, the adverse effects of complex groundwater matrices could be overcome by increasing the molar ratio of oxidant/Fe(II)/chlorobenzene.

Summary: The application of calcium sulfite (CaSO3) as a substitution for common S(IV) sources for the regeneration of Fe(II) was investigated. CaSO3 had advantages including sustained supplement of SO32- for Fe(II) regeneration, lower cost and toxicity, increased concentration of reactive species, and formation of CaSO4 precipitate after the reaction. In the presence of CaSO3, the removal of trichloroethylene (TCE) and other organic contaminants was significantly promoted and different enhanced systems had high tolerance on complex solution conditions. The major reactive species in different systems were determined through qualitative and quantitative analyses.

Summary: The aim of this study is to characterize the degradation products of lead weights from an important Steinway & sons piano. The results showed that hydrocerussite is the main degradation product on the superficial layer of lead weights, followed by lead acetate and formate. Exposure of lead weights to formic and acetic acid vapours promotes the formation of basic lead formate, which leads to the formation of hydrocerussite. These results can preserve the sound of the piano by limiting the degradation of its components.
