The objective of this work was to verify the sorption properties of granular filter materials (GEH, CFH12, Bayoxide E33) during the process of removing antimony from water, and to monitor the impact of magnetic and electromagnetic fields on the effectiveness of removing antimony from water. Pilot tests showed that the use of iron-based sorption materials could possibly decrease the antimony content in water to the values limited for drinking water (5 μg/L Sb). The most suitable adsorbent for removing antimony was GEH. At a concentration of antimony in raw water of 81.4 μg/L and a filtration rate of 3.4 m/h, a value of bed volume 2,030 and adsorption capacity of 144.7 μg/g was determined; at the filtration rate of 5.6 m/h, the bed volume was 1,342, and the adsorption capacity was 96.8 μg/g achieved at breakthrough concentration 5 μg Sb/L. The results presented from testing the effects of a permanent magnet and electromagnet in removing antimony are not well known, as only a few experiments have been conducted.
