Abstract：
:Zero-valent iron nanoparticles (NZVI) as well as polymer-stabilized nanoparticles were synthesized and used for lindane (γ-hexachlorocyclohexane) degradation in aqueous solution. To study the effectiveness of the different coated nanoparticles, simple and rapid analytical methods have been developed to measure and to detect lindane and its by-products. For the monitorization of lindane degradation solid-phase extraction (SPE) was used, while volatile by-products formation measurement was carried out by headspace-solid phase microextraction (HS-SPME) followed by GC/MS. The SPE-GC/MS method provides low detection limits (0.2 μg L(-1)), high recovery (above 95%) and it is a valuable tool for kinetic studies of the degradation process for each polymer used, while HS-SPME-GC/MS has proved to be an effective tool for the extraction and evaluation of volatile degradation by-products.
