The aim of this project was to study the treatment of industrial waste using ETS-10 zeolite. The pollutants that must be removed were metals sourced from zinc ferrite, a processing waste derived from the use of mineral-containing zinc. The first phase of the work involved the characterization of the industrial waste, zinc ferrite, in order to deepen the knowledge regarding its nature and composition. The second phase involved the removal of the metals released by the zinc ferrite in aqueous systems using the ETS-10 phase as an ion exchanger. Different chemical and physical techniques were used: plasma mass spectrometry, X-ray diffraction, scanning electron microscopy, microanalysis, and thermal analyses. A comparison between ETS-10 and commercial zeolite A performance, in the same aqueous systems, was carried out. The results showed that the metal removal efficiency of ETS-10 phase is higher than that obtained by commercial zeolite A, especially towards dangerous heavy metals such as Pb, Zn and Mn.
本项目的目的是研究使用ETS - 10沸石处理工业废物。必须去除的污染物是来自锌铁氧体的金属,锌铁氧体是一种源自含锌矿物使用的加工废料。工作的第一阶段涉及对工业废物锌铁氧体进行表征,以加深对其性质和成分的了解。第二阶段涉及使用ETS - 10相作为离子交换剂去除锌铁氧体在水体系中释放的金属。采用了不同的化学和物理技术:等离子体质谱、X射线衍射、扫描电子显微镜、微分析和热分析。在相同的水体系中对ETS - 10和商用A型沸石的性能进行了比较。结果表明,ETS - 10相的金属去除效率高于商用A型沸石,尤其是对铅、锌和锰等危险重金属。
