Synthesis and characterization of zeolite LTA by hydrothermal transformation of a natural Algerian palygorskite
Source abstract
Abstract
A palygorskitic-rich Algerian clay (Sif Pal) has been selected as Si source to synthesize zeolite LTA through a hydrothermal treatment by using sodium aluminate. Sif Pal is activated under reflux using hydrochloric acid solutions at different concentrations (4, 6 and 7 mol.L) in a ratio of 50 g.L and then analysed using XRD, SEM and XRF analysis. The selected product (PalH1) is mixed with NaOH solutions at different concentrations (1, 2, 3, 4 and 5 mol.L), diverse NaAlO quantities (1, 2, 3 and 5 g) and analysed after several nucleation (1, 2, 3 and 5 h) and crystallization (6, 18 and 24 h) times to check the influence of these parameters on the synthesis of zeolite LTA. To obtain almost pure (> 98%) zeolite LTA, the better experimental conditions were: 3 mol.L of NaOH solutions, 3 g of sodium aluminate, 3 h for nucleation and 24 h for crystallization.
