Release of heavy metal contaminated wastewater is one of the major problems being encountered by many industries due to its hazardous effect on the ecosystem, specifically its negative impacts on human health. Although essential in small quantities, nickel (Ni) and other heavy metals could be very dangerous to human health when uptaken at high concentrations. In this regard, this undertaking focused on the fabrication of nanofibers of cellulose acetate (CA) with varying concentrations (0, 1.0, 1.2 and 1.4 wt%) of iron-modified nanozeolite (Fe-MNZ) through electrospinning technique for the adsorption of Ni2+ ions in simulated wastewater. The membranes produced underwent different characterization techniques to determine the effect of Fe-MNZ addition on the nanofibers. FTIR result showed changes in the broadness of some bank peaks which signifies the interaction between CA and Fe-MNZ. SEM results showed increasing fiber diameter with increasing Fe-MNZ concentration having an 848.08 nm maximum diameter. Lastly, Freundlich isotherm and pseudo-first order kinetics govern the adsorption of the Ni2+ ions, with the highest adsorption capacity of 7.46 mg Ni2+/g membrane.
