Abstract
Invenţia se referă la un procedeu de purificare a apei concomitent de ioni de fluor şi acizi humici.Procedeul, conform invenţiei, include trecerea apei cu viteza fluxului de 0,3 dm3/min printr-un volum de 14…28 cm3 de sorbent pe bază de diatomit modificat cu hidroxid de aluminiu fin dispersat. Diatomitul modificat se obţine prin mărunţirea şi calcinarea acestuia, menţinerea într-o soluţie a sării de aluminiu, tratarea cu soluţie de amoniac, filtrarea, spălarea şi uscarea la aer.
