Maredan clay is a natural material that potential as a raw material for making zeolite synthesis. Zeolite from Maredan clay was used as an adsorbent to adsorb lead(II) metal. Purpose of experiment to synthesis zeolite from Maredan clay due to high SiO2 and Al2O3 contains. Maredan clay was characterized used XRF to determinethe oxide contain. The method used in zeolit sythesis is alkaline hydrot…
