“…In this study, the removal of methyl orange dye from aqueous solutions was performed and studied using activated carbon as an adsorbent material. The optimal conditions of the studied remediation process were determined through experiments in which four operational parameters were varied: dosage effect (0.001-0.010 g AC), interaction time (1-120 min), MO concentration (5-100 mg/L MO), and pH (3)(4)(5)(6)(7)(8)(9)(10)(11). pH and adsorbent dosage proved to be the most influential parameters for the adsorption of MO.…”

“…Researchers have used different approaches over time, such as physical, chemical, or biological processes, in order to mitigate environmental metals, dyes, and other organic pollutants [8][9][10][11][12]. Micellar solubilization is also a widely used method for organic pollutant removal from aqueous solution, incorporating them into or onto micelles [13][14][15].…”

This research investigates commercial activated carbon (AC) potential to remove methyl orange (MO) dye removal from aqueous solution using a batch process. The AC material was characterized using FTIR spectroscopy and SEM analysis. The effect of the main operating parameters, such as the pH, adsorbent dosage, contact time, and initial dye concentration, was studied. MO removal could be accomplished within 30 min at a pH value of 3. The calculated maximum MO adsorption capacity onto activated carbon was 129.3 mg/g, while the removal efficiency was 97.8%. Adsorption results were analyzed by studying the Langmuir and Freundlich isotherm models. The MO adsorption data on activated carbon were better explained by the Langmuir isotherm than by the Freundlich isotherm. The pseudo-second-order kinetic model may have had an effect on the MO dye adsorption on AC material. This research showed that the commercial activated carbon can be used as an effective sorbent for MO removal from wastewater sample. Moreover, the AC material has good reusability and practical utilization capacities.
