Studying the removal of rhodamine B (RB) dye by using zeolite 13X molecular sieves supported by Fe 2 O 3 nanoparticles (denoted as Fe 2 O 3 -13X) is the main objective of this study. Fe 2 O 3 -13X was synthesized and modified by the addition of sodium dodecyl sulfate (SDS). e prepared Fe 2 O 3 -13X was characterized by XRD, TEM, SEM, and zeta potential. e effects of the solution pH, SDS amount, contact time, initial dye concentration, and adsorbent dosage on the removal efficiency of RB were studied. A maximum removal efficiency of 99.3% was achieved. e adsorption equilibrium data of RB were fitted using the Freundlich model, yielding the maximum adsorption capacity of 89.3 mg/g. e findings revealed that the RB adsorption onto Fe 2 O 3 -13X modified with SDS (Fe2O3-13X-Ms) was described by a pseudo-second-order kinetic equation. e results reported in this paper indicate that a high RB removal percentage was attained by adding SDS to Fe 2 O 3 -13X.

“…Some interesting variations to the former examples are also reported. The most directly related was presented by Lee et al The authors started from a similarly prepared Fe(II) natural clinoptilolite zeolite (Pohang, Korea), but promoted reduction of the iron ions to the zerovalent state with sodium borohydride [133]. The authors used this support for the simultaneous treatment of diluted Cd(II) and Cr(VI) solutions.…”

This review aims to present a global view of the efforts conducted to convert zeolites into efficient supports for the removal of heavy metal oxyanions. Despite lacking affinity for these species, due to inherent charge repulsion between zeolite framework and anionic species, zeolites have still received considerable attention from the scientific community, since their versatility allowed tailoring them to answer specific requirements. Different processes for the removal and recovery of toxic metals based on zeolites have been presented. These processes resort to modification of the zeolite surface to allow direct adsorption of oxyanions, or by combination with reducing agents for oxyanions that allow ion-exchange with the converted species by the zeolite itself. In order to testify zeolite versatility, as well as covering the wide array of physicochemical constraints that oxyanions offer, chromium and arsenic oxyanions were selected as model compounds for a review of treatment/remediation strategies, based on zeolite modification.
