Synthesis of zeolite L from natural zeolite by the alkali fusion -hydrothermal method
In this work, zeolite L synthesis conditions by using the hydrothermally-assisted alkaline fusion method and its ion exchange capacity are studied. To obtain zeolite L, natural zeolite, Al(OH)3 y KOH at a concentration of 0.66 and 2.66 M were mixed. The mixture was calcined at 400 °C for 2 hours and...

| Summary: | In this work, zeolite L synthesis conditions by using the hydrothermally-assisted alkaline fusion method and its ion exchange capacity are studied. To obtain zeolite L, natural zeolite, Al(OH)3 y KOH at a concentration of 0.66 and 2.66 M were mixed. The mixture was calcined at 400 °C for 2 hours and subsequently, the synthesis reaction was carried out in a hydrothermal reactor at 145 °C for 50 and 90 hours. The zeolite was analyzed using X-ray Diffraction, Scanning Electron Microscopy and Inductively Coupled Plasma Mass Spectrometry characterization methods. Ion exchange was carried out at 25 °C for 24 hours by mixing Cu(NO3)2 at 1000 ppm with the synthetic zeolites obtained and their Cu2+ ion absorption capacity was analyzed using the UV-Vis spectrophotometry method where it was found that the synthesized zeolite absorbed more Cu2+ ions than the natural zeolite. |
