The interaction of cetyltrimethylammonium bromide (CTAB) with orange II has been studied spectrophotometrically. CTA‐Orange II complex was isolated from an aqueous solution with chloroform. The results indicate that the CTAB interacts in 1:1 stoichiometry with orange II. CTAB capped FeNPs were used as an adsorbent to the removal of CTA‐Orange II complex. Energy dispersive x‐ray spectroscope (EDX), Fourier transform infrared spectroscope (FTIR), surface scanning microscope (SEM), and transmission electron microscope (TEM) were used to determine the morphology of FeNPs. The effect of contact time, pH, and concentration of orange II were examined on the removal of dye and surfactant. The removal of orange II followed pseudo‐second‐order kinetic and Langmuir isotherm model. The maximum adsorption capacity (Qmax) of CTAB‐FeNPs for orange II was 1288.9 mg/g at 30°C. CTA‐Orange II complex was adsorbed onto the adsorbent through several types of interaction (e.g., electrostatic attractions, van der Waals interactions, hydrogen bonding and n‐π stacking interactions). The sorption of orange G was also studied at different CTAB concentrations. The results implied that the maximum sorption amount was almost half of the orange II adsorption. The findings reveal the feasibility of CTAB capped FeNPs to be used as an excellent and low‐cost adsorbent for the removal of various water pollutants, more specifically anionic dyes.

“…Synthetic dyes, in particular, can be extremely dangerous even in small amounts, as they can cause cancer and mutations (7). These dyes are commonly used in various industries such as textiles, paper, pulp, tanneries, and pharmaceuticals due to their affordability, vibrant hues, ability to withstand environmental factors, and ease of application (8). The widespread use of these dyes has led to a significant amount of pollution being released into water systems.…”

Fly ash (FA) and modified fly ash (mFA) were used as adsorbents to remove methylene blue (MB) dye from aqueous solutions. The adsorbents were characterized using crystal structures with XRD, surface functional groups with FTIR, and surface morphologies with SEM. Response surface methodology (RSM) with Box-Behnken design (BBD) was used to optimize adsorption parameters such as MB dye concentration (A: 10-20 mg/L), solution pH (B: 3-11), and contact time (C: 30-180 min). ANOVA analysis shows the significant inter-actions between initial concentration, solution pH value, and solution pH value, contact time was found to be significant in the removal of MB (p-value=< 0.0001, 0.0040), whereas between the effect of initial concen-tration and contact time was not significant (p-value = 0.0881). The adsorption kinetics followed the pseudo-second-order (PSO) kinetic model and the adsorption isotherm followed the Langmuir model. At 28°C, the adsorption capacity of fly ash-HNO3 for MB was found to be 7.67 mg/g.

“…Among these methods, one of the most effective, feasible, and economical method is the adsorption of dye molecules by the porous material. 9,10 Various adsorbent materials have been employed for dye capture, such as carbon materials, 11,12 biopolymers, 13,14 metalbased materials, 15,16 organic polymers and their composites, [17][18][19] including metal-organic frameworks (MOFs). [20][21][22][23][24][25][26][27][28][29][30][31][32] MOFs can be tailored based on the precursor metal salts/ligand moiety and by post-synthetic modification to neutral or charged (cationic/anionic) MOFs, and most commonly used ionic dyes in the industry can be readily separated by the ion-exchange process using ionic MOFs.…”
