Improving the efficiency of Cr( vi ) reduction and adsorption by Fe 3 O 4 using ZSM-5 zeolite support prepared through various methods

The study involved the synthesis of magnetite (Fe 3 O 4 ) and zeolite-supported Fe 3 O 4 (Fe/Z) using co-precipitation (COP) and hydrothermal (HYD) methods which proved effective for removing Cr( vi ) from contaminated water.
