Facile Synthesis of Cobalt Ferrite (CoFe2O4) Nanoparticles in the Presence of Sodium Bis (2-ethyl-hexyl) Sulfosuccinate and Their Application in Dyes Removal from Single and Binary Aqueous Solutions

Abstract

A research study was conducted to establish the effect of the presence of sodium bis-2-ethyl-hexyl-sulfosuccinate (DOSS) surfactant on the size, shape, and magnetic properties of cobalt ferrite nanoparticles, and also on their ability to remove anionic dyes from synthetic aqueous solutions. The effect of the molar ratio cobalt ferrite to surfactant (1:0.1; 1:0.25 and 1:0.5) on the physicochemical properties of the prepared cobalt ferrite particles was evaluated using different characterization techniques, such as FT-IR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption analysis, and magnetic measurements. The results revealed that the surfactant has a significant impact on the textural and magnetic properties of CoFe2O4. The capacity of the synthesized CoFe2O4 samples to remove two anionic dyes, Congo Red (CR) and Methyl Orange (MO), by adsorption from aqueous solutions and the factors affecting the adsorption process, such as contact time, concentration of dyes in the initial solution, pH of the media, and the presence of a competing agent were investigated in batch experiments. Desorption experiments were performed to demonstrate the reusability of the adsorbents.

“…Other peaks in the spectra are attributed to vibrations of other of H-O, and C-O, functional groups [17]. Because the large surface area of such materials, they are also attributed to bending and stretching resonance of H2O absorbed as from atmosphere when the samples were maintained and processed in the air [18]. The Peaks observed on the range of 1986-2343 cm −1 are instrument-based of CO2 background in the sample [19].…”

“…Table 1 shows the surface area, pore volume, and pore size characteristics of CoNiPr x = 0.00, 0.02, 0.04, 0.06, and 0.08, respectively. CoNiPr (x ≤ 0.10) NSFs without Pr (x = 0.00) exhibit a typical H2 hysteresis loop corresponding to that of cubic-shaped pores [23]. For CoNiPr (x ≤ 0.10) NSFs with x = 0.02, 0.04, 0.06, and 0.08, variation in the pore width reflects the influence of Pr on narrow pore body distributions with a wide neck.…”
