Synthesis and Characterization of Magnetic Fe₃O₄/Zeolite NaA Nanocomposite for the Adsorption Removal of Methylene Blue Potential in Wastewater Treatment

Figure 3

Micro-Raman spectra of zeolite A as-synthesized Fe₃O₄ NPs and Fe₃O₄/ZA nanocomposite samples with different Fe₃O₄ NP loadings (wt. %). The optical microscope images of the probed area (dash rectangles) are presented right next to their corresponding spectrum.
