Tiivistelmä
Water contamination is a critical global issue, necessitating efficient and sustainable remediation strategies. Adsorption stands out as a promising solution, particularly when using natural, abundant, and sustainably sourced adsorbents. This study focuses on enhancing the sorptive properties of natural soil minerals through thermal activation, a method valued for its accessibility and effectiveness.
The activated minerals underwent comprehensive characterization, with compositional changes confirmed via XRF and SEM-EDS, phasic transformations verified by XRD, and thermal stability assessed using TGA. The results demonstrated that thermally activated minerals significantly improved contaminant immobilization in wastewater and water-sediment systems from a real reservoir. However, the materials were less effective in soil applications, highlighting the importance of contextual suitability in remediation efforts. This study underscores the potential of thermally activated natural minerals in sustainable water treatment, while also pointing to the need for further research into optimizing soil remediation techniques.
