САЖЕТАК / ABSTRACT:
In this study, clay from the Kolubara mine in Serbia was used to make filters as a separation media. This study, as a consequence, explores the scientific area of developing porous materials from natural minerals and areas of environmental protection. After clay purification, H3BO3 contents of 2 wt.% and 0.5 wt.% were used as a low-cost, environmentally friendly chemical to create a porous structure. The influence of different amounts of H3BO3 on the separation ability of the clay filter was monitored. Additionally, various synthesis conditions, such as low pressing pressure of up to 60 MPa and low sintering temperatures of 1150 oC and 1300 oC were applied to prepare the filter medium with good separation and mechanical properties, such as good strength and Young’s modulus.
