Improving the efficiency of Cr(vi) reduction and adsorption by Fe₃O₄ using ZSM-5 zeolite support prepared through various methods.

ABSTRACT: The study involved the synthesis of magnetite (Fe₃O₄) and zeolite-supported Fe₃O₄ (Fe/Z) using co-precipitation (COP) and hydrothermal (HYD) methods which proved effective for removing Cr(vi) from contaminated water. X-ray diffraction (XRD) analysis showed that the Fe₃O₄ phase had a cubic crystal structure. The COP method resulted in lower crystallinity compared to the HYD method. The different preparation methods also led to variations in the morphologies and sizes of the Fe₃O₄ particles. The HYD-prepared sample exhibited a uniform spherical shape with sizes of 400-500 nm, while the COP-prepared samples showed rod-like and granule shapes with smaller particle sizes of 20-50 nm. The study also investiga
