Abstract
Inventia se refera la un procedeu de obtinere a sorbentului pe baza de diatomit pentru purificarea lichidelor de ionii de fluor. Procedeul, conform inventiei, include maruntirea diatomitului, tratarea consecutiva a acestuia cu solutie de hidroxid de sodiu de 1…3 M in raportul diatomit:baza de 0,65…1,35, la temperatura de 50…60°C timp de 30…90 min, cu solutie de sare de aluminiu de 1,25…1,50 M in raportul atomar Al:Si de 1,95…2,50 la un pH mai mic de 3,5 timp de 2…5 ore la agitare si cu solutie de amoniac de 25% la un pH mai mare de 9 timp de 2…5 ore la agitare, cu spalarea ulterioara pana la un pH neutru, uscarea la aer timp de 24 ore, precum si la temperatura de 120…130°C timp de 2 ore.
