| Sumari: | Title screen Development of cheap and reliable methods of water purification is worldwide challenge. Application ofsorbents is one of the most efficient and universal method of water purification, but it has drawbacks. Designingof new efficient sorbent is topical task. The main goal of this study was investigation of the new sorbent basedon the aerated concrete. The aerated concrete sorbentwas used in intact condition and after modification. Thecomposition of thesorbents was determined by elemental analysis with emission spectroscopy. Zeta potential ofwater suspension was evaluated by Zetasizer Nano. The low leaching level into water for all tested sorbents wasdetermined. The properties of the filtering materials have been determined by sorption test of removing bacteriaEscherichia coli from the model suspension. The surface parameters were investigated, using the method ofthermal desorption of nitrogen. The tested filters with fraction of less than 0.1 mm clean the bacterial suspensionto the level of compliance with hygiene standards for drinking water. It was revealed satisfactory properties ofthe filtering material for water purification from microbiological contaminations. The results prove thepossibility of using the aerated concrete for water purification. |
