“…At higher SDS concentrations, RB adsorption decreased because of the aggregates of SDS in the solution, which can hinder the micelle formation on the adsorbent surface. Similar ndings were reported by Shariati et al, who modi ed Fe 3 O 4 nanoparticles with SDS and utilized it to remove safranin O [36].…”

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.

“…From the peaks of the spectrum corresponded to the Bragg reflections, the structure of synthesized Fe 3 O 4 MNPs was obtained as a cubic crystal phase [49]. The absence of the Fe 3 O 4 peaks below 2u angle of 30 was also proof that the black powder was Fe 3 O 4 and therefore, no impurities of Fe 2 O 3 were observed [50]. Also, Fig.…”

“…The parameters obtained from different models provide important information about the adsorption mechanism, the surface properties and affinity of the adsorbent [45]. The common models for investigation of the adsorption isotherm (Langmuir and Freundlich) were also fitted to the experimental data [23].…”

This work evaluates the efficiency of SiO 2 -coated Fe 3 O 4 magnetic nanoparticles (SMNPs) for adsorption of methyl orange (MO). Adsorption of MO on the studied nanoparticle was developed for removal, preconcentration and spectrophotometric determination of trace amounts of it. To find the optimum adsorption conditions, the influence of pH, dosage of the adsorbent and contact time was explored by central composite design. In pH 2.66, with 10.0 mg of the SMNPs and time of 30.0 min, the maximum adsorption of MO was obtained. The experimental adsorption data were analyzed by the Langmuir and Freundlich adsorption isotherms. Both models were fitted to the equilibrium data and the maximum monolayer capacity q max of 53.19 mg g -1 was obtained for MO. Moreover, the sorption kinetics was fitted well to the pseudo-second-order rate equation model. The results showed that desorption efficiencies higher than 99 % can be achieved in a short contact time and in one step elution by 2.0 mL of 0.1 mol L -1 NaOH. The SMNPs were washed with deionized water and reused for two successive removal processes with removal efficiencies more than 90 %. The calibration curve was linear in the range of 10.0-120.0 ng mL -1 for MO. A preconcentration factor of about 45 % was achieved by the method.
