“…Figures –a–c show the micrographs of the zeolites synthesized from thermally treated metakaolin using 2.5 M NaOH, which reveals the “sugar cube” shaped morphology. The morphology is formed due to the secondary building unit (SBU) of the sodalite cage interconnected by using D4R, which results in the formation of a three-dimensional (3D) micropore cubic structure (α-cage) morphology. , The particle size of the synthesized zeolites is found to be in the range of 1.9 to 2.2 μm with an average of 2 μm for the zeolite synthesized using 2.5 M NaOH. Figures –e–g are the micrographs of the zeolites synthesized using 3 M of NaOH.…”

Making use of low-cost zeolite adsorbents for CO2 adsorption is an encouraging technique for the adsorption of the CO2 gas emitted from flue gases. In the present work, the zeolites were successfully synthesized from kaolin by the conversion of metakaolin and also by using 2.5 and 3 M of NaOH. The transformation of kaolin into metakaolin was achieved through a thermal treating process for 4 h at various temperatures such as 600, 700, 800, and 900 °C. The molar ratio used for the synthesis was X Na2O:Al2O3:1.926 SiO2:128 H2O (where X = 2.5 and 3 M of NaOH). The 2.5 and 3 A (600–900 °C) zeolite was synthesized through the hydrothermal process without using any organic template agent. The “sugar cube” and octahedral-shaped morphology are observed through FESEM and TEM analysis. The textural properties of the synthesized samples were found using N2 adsorption/desorption studies. The type IV and type I adsorptions were identified from the sorption studies. However, the CO2 sorption studies are recorded at 297.15 K, and the type I adsorption isotherms were observed according to the IUPAC classification criterion. The experimentally observed data were fitted by nonlinear regression curve fit using a Langmuir, Freundlich, and Toth adsorption isotherm, and their parameters were recorded.

“…Kaolin is a low-cost raw material and is abundant across the world. When kaolin is used as a synthetic raw material, Na-A zeolites can be obtained by dissolving metakaolin in a sodium hydroxide (NaOH) solution without adding any other silica or alumina sources [11].…”

Sr2+ ions in an aqueous solution were removed using Na-A zeolites synthesized from kaolin, a natural mineral. Na-A zeolites with high crystallinity were synthesized using NaOH/kaolin mass ratios of 0.6 (ZK06) and 0.9 (ZK09). The adsorption reached equilibrium within 120 min. The adsorption data obtained from experiments for Sr2+ using ZK06 and ZK09 were appropriately analyzed with pseudo-second-order kinetic and Langmuir isotherm models. Comparing the maximum adsorption capacities (qm) of ZK06 and ZK09 for Sr2+, the highest values were obtained at 1.90 and 2.42 mmol/g, respectively. Consequently, the Na-A zeolites synthesized from kaolin can be evaluated as adsorbents with high adsorption capacities for the removal of Sr2+, proportional to the degree of their crystallinity.
