Abstract

In this paper, the low-cost and practical adsorption for removing methylene blue (MB) dye has been developed by using recoverable natural zeolite that was magnetized with Fe3O4. The magnetization was conducted by co-precipitation technique. The adsorbents obtained from the magnetization were characterized by XRD, FTIR, surface area analyzer and turbidity meter machines. The MB adsorption on the recoverable adsorbent was performed by batch experiment. In this study, the effect of Fe3O4 fraction on the recoverability and adsorption ability of the adsorbent was evaluated and the adsorption kinetic was also determined. The research results attributed that recoverable zeolite/Fe3O4 adsorbent has been successfully produced. It was found that the increase of Fe3O4 fraction in the adsorbent, has improved the recoverability, but in the same time, it caused the adsorption decreased. The fraction of Fe3O4 as much 33.30w displayed compromisingly good capacity and recoverability. The maximum MB dye adsorption was reached by using 0.25 g L-1 of the adsorbent dose, pH 8, and in 60 min of the contact time. The adsorption kinetic well fitted with pseudo second-order with the adsorption rate of 0.0238 mg g-1 min-1. The adsorption strongly agreed with the Langmuir isotherm with adsorption capacity of 32.258 mg g-1. © 2021 Global NEST.
