Abstract
Invenţia se referă la domeniul obţinerii sorbenţilor anorganici şi poate fi utilizată pentru purificarea apei de ionii de fluor şi de acizii humici.Materialul de filtrare-sorbţie pentru purificarea apei conţine hidroxid de aluminiu nanodimensional pe diatomit activat, totodată conţinutul hidroxidului de aluminiu recalculat la Al2O3 constituie 12…19%, diatomit activat - restul.Procedeul de obţinere a materialului de filtrare-sorbţie pentru purificarea apei include mărunţirea diatomitului, menţinerea lui în soluţia sării de aluminiu, tratarea cu soluţie de amoniac la un pH mai mare de 9 timp de 2…5 ore, filtrarea, spălarea, uscarea la aer, totodată după mărunţire se efectuează calcinarea diatomitului la temperatura de 400…450°C, iar menţinerea se efectuează în soluţia sării de aluminiu 2M la temperatura de 50…60°C, timp de 1…3 ore la agitare continuă.
