Characterization of Synthesized Zeolite from Iraqi Metakaolin and its application in dye removal from wastewater

Abstract

The present work aims to synthesise and characterise Zeolite using Iraqi metakaolin and to study their performance in the removal of dye from wastewater. Techniques such as scanning electron microscope SEM, X-ray diffractometer XRD, and FTIR Fourier transmission infrared spectrometer were used to synthesise zeolite characterisation.  A UV spectrometer determined zeolite's efficiency in removing RB dye from wastewater. The X-ray diffraction result for the zeolite prepared showed that the zeolite was identical in structure to the commercial zeolite Type A. The prepared zeolite was examined as an adsorbent to remove RB dye from wastewater. The adsorption Experiment revealed that approximately 13 ppm of dye could be removed per 2 grams of zeolite, which was deemed unsatisfactory and compatible with similar studies. Additionally, adsorption isotherms modelling indicated that the Langmuir model best described the adsorption behaviour, suggesting a monolayer adsorption process.
