“…In this study, the central composite design (CCD) coupled with the RSM was implemented to maximize ACN removal at optimum wastewater pH, activated carbon dosage, and contact time of adsorbent and wastewater. The CCD is one of the most widely used quadratic design techniques among experimental matrix designs [24]. It is developed using random experimentation to test for lack of fit without using a significant number of design points [25].…”

Application of the Response Surface Methodology (RSM) in the Optimization of Acenaphthene (ACN) Removal from Wastewater by Activated Carbon

The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater has raised concerns about human health due to their potential carcinogenic and mutagenic properties. The widespread use of products containing acenaphthene (ACN, one of the 16 priority PAHs) in many industries and large-scale ACN release into the wastewater has resulted in dangerous concentrations of ACN in the environment. As a result, before discharge, it is required to eliminate or reduce its concentration to an acceptable level. Adsorption is an effective method of removing PAHs from wastewater. In this study, the ACN adsorption reaction in sample wastewater was evaluated using activated carbon produced by oil palm leaves. HPLC was used as an analytical method for quantifying ACN in wastewater samples. The initial concentration of ACN in water samples was 9.58 ± 0.5 mg/L. The experiments were conducted using the CCD combined with the RSM and using three independent variables, i.e., pH, activated carbon dosage (g/L), and contact time (min), and one dependent variable, i.e., ACN removal efficiency (%). The ANOVA was used to identify the significance of the developed model in the RSM. Lastly, the RSM was used to optimize the adsorption results. The experimental results determined that the removal of 98.73 ± 1% of ACN (the highest amount) was achieved at pH 7, while the removal of 88.44 ± 1% of ACN (the lowest amount) was achieved at pH 4.5. The adsorption efficiency of ACN was slightly increased by an increase in activated carbon dosage from 0.1 to 3 g/L (<4%). The contact time was the most significant factor in controlling the adsorption efficiency of ACN in wastewater, and not pH value or dosage. The adsorption reaction was quick, and 88–90% of ACN was removed within 5 min of the adsorption reaction, followed by slower adsorption for up to 90 min. The RSM model was developed on the basis of experimental results. An ANOVA determined that the developed model was significant enough to represent the adsorption data as the p-value was <0.05 for the model. The factors pH, adsorbent dosage, and contact time were also significant factors (p-value < 0.05). The optimization results showed that pH of 6.96, adsorbent dosage of 2.62 g/L, and contact time of 71.67 min were the optimal conditions for eliminating 98.88% of the ACN. The optimization results were verified in the lab, and a close agreement was found between the predicted results of the RSM and experimental results. The study found that the RSM is an effective tool for optimizing operating variables, as well as for significantly reducing time and experimentation costs.

Since benzothiophene (BT) is a typical S-containing compound in commercial fuels, proper adsorbents with desirable BT capture ability need to be developed. A novel magnetism-bimetallic Fe 3 O 4 @Zn/Cu-BTC composite has been synthesized via a simple one-pot method for the removal of BT from mixed model fuel. SEM, XRD, XPS, and BET characterizations described the as-prepared Fe 3 O 4 @Zn/Cu-BTC. BT uptakes over Fe 3 O 4 @Zn/Cu-BTC reached 85 mg/g, which is superior to those of previously reported in literature. Batch adsorption studies revealed that the adsorption process obeyed pseudo-second order kinetic model, the determining step might be chemical sorption, and adsorption equilibrium could be achieved within 30 min.Among various isotherm models, the experimental data for adsorption of BT followed the Langmuir isotherm best. Thermodynamic parameters demonstrated that BT adsorption process was endothermic and spontaneous. Importantly, Fe 3 O 4 @Zn/Cu-BTC could be easy obtained from liquid through Fe 3 O 4 magnetism, and has high stability and good reusability, which might be beneficial for further practical deep desulfurization.

In this work, raw sunflower seed shell particles (RSSSP) as a green adsorbent were used to remove disperse red 1 (DR1), crystal violet (CV), and malachite green (MG), and methylene blue (MB) dyes from synthetic wastewater. Various analyzes, including fourier transform infrared, field-emission scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller analysis, were performed, which determined the morphology, particle size, surface area, and pore size of RSSSP. The effect of environmental factors on the adsorption ability of the RSSSP was investigated in detail. The results of this study showed that RSSSP has high adsorption efficiency toward organic dyes, and was comparable with other natural and synthetic adsorbents. The results showed that Freundlich isotherm and pseudo-second-order models describe the adsorption of the dye onto RSSSP. Additionally, the maximum adsorption capacity of DR1, CV, MG, and MB onto RSSSP was found to be 85, 81, 120, and 98 mg/g, respectively. Fur-
