Synthesis and Characterization of nanoClinoptilolite /cobalt oxidenanocomposite

Zeolites, a member of the microporous crystalline aluminosilicates family, also known as“molecular sieves”. Zeolite has the three-dimensional structures which are composed of thenetworks of [SiO۴]۴− and [AlO۴]۵− tetrahedral linked to each other with oxygen atoms .Naturalzeolites are abundant in nature and have operational importance, including: clinoptilolite. mordenit[۱].This work synthesis an novel adsorbent nanozeolite/Co۳O۴ (NZC) with high adsorptioncapacity by combining modified natural clinoptilolite nanozeolite and cobalt oxide to enhance theadsorption ability of zeolite. Characterization of the final nanocomposite was done by XRDpattern, Field Emission Scanning Electron Microscope (FE-SEM) and Energy-dispersive X-rayspectroscopy (EDS). The XRD pattern results confirmed the correctness of the nanocompositesynthesis and SEM images and EDS reveal the appropriate particle size and element distribution.The prepared adsorbent can be used to absorb cationic pollutants and heavy metals [۲-۴].
