This work addresses the processing of large-scale agricultural waste – rice husk, which is utilized as a source of silicon for the synthesis of sodium aluminosilicate. A method for producing sorbents, in particular an aluminosilicate adsorbent for the purification of natural and wastewater in various industrial sectors, is described. As a result of mixing 50 ml of a saturated aluminum sulfate solution with sodium silicate (obtained by microwave irradiation of a mixture of 130 ml of 1 M sodium hydroxide solution with 10 g of ground, distilled water-washed, and air-dried rice husk), a precipitate is formed. Subsequent thermal treatment of this precipitate at different temperatures yields sorbents with varying sorption characteristics. This method of producing sodium aluminosilicate from rice husk is efficient and environmentally sustainable, enabling the utilization of agricultural waste while obtaining valuable adsorbents with high performance.
