“…Thus, RSM overcomes situations requiring a large number of experiments minimizing additional chemicals, time, and expensive analysis, promoting a reduction of extra costs (Biswas et al 2019;Şahan 2019). RSM advantages guaranteed its application in several works regarding the removal of contaminants from water to process parameter optimization, such as adsorption (Kaynar et al 2018;Biswas et al 2019;Deng and Chen 2019;Hasan and Setiabudi 2019;Kaur et al 2019;Şahan 2019;Sharifpour et al 2019;Wakkel et al 2019), electrocoagulation (Barsç and Turkay 2016;Murdani et al 2018;Rabahi et al 2018;Deveci et al 2019;Karamati-Niaragh et al 2019), Fenton reaction (Saeed et al 2015;Xie et al 2016;Liu et al 2018), electrochemical oxidation (Garg and Prasad 2015;Domínguez et al 2016;Darvishmotevalli et al 2019;Duarte et al 2019), and photocatalytic degradation (Mirzaei et al 2018;Galedari et al 2019;Karimi et al 2019).…”

The palm (Elaeis guineensis), known as dendê, is an important oleaginous Brazilian plant with a high performance of oil production. In this work, a 2 3 full experimental design was performed and the response surface method (RSM) was used to indicate the optimum parameter of caffeine adsorption on Elaeis guineensis endocarp activated carbon, since the endocarp is the main by-product from dendê oil production. It was set the adsorbent point of zero charge (pH pzc), and the material was characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The RSM results indicate removal efficiency (%) at the optimal conditions, 0.20 g of adsorbent, and caffeine initial concentration of 20 mg/L, and acidic medium was about 95%. Based on ANOVA and F test (F calculated > F standard), the mathematical/statistical model obtained fits well to the experimental data. The overall kinetic studies showed time was achieved after 5 h and caffeine adsorption followed the pseudo-second-order model suggesting chemisorption is a predominant mechanism. Redlich-Peterson and Sips models best represented the experimental data (0.967 < R 2 < 0.993). Thermodynamic revealed that caffeine adsorption was spontaneous at all temperatures studied, exothermic, and probably with changes in the adsorbate-adsorbent complex during the process. The tests conducted in different water matrixes corroborate the suitability of this adsorbent to be used in caffeine removal even in a complex solution.

“…Rabah et al. 94 utilized aluminum electrodes in a batch system and RSM was adopted to model and optimize the EC process for treatment of leachate effluent. In addition, the influence of key independent parameters such as current density, initial pH, time duration ( X 3 ), and distance between electrodes on % COD response was examined.…”

Electrocoagulation (EC) is a well‐recognized and feasible treatment technique for wastewater treatment. The process optimization and analysis of process parameters of EC not only aid to scale up the EC process at an industrial level but also help to explore the economic and environmental considerations to achieve higher efficiency. Response surface methodology (RSM) is a prominent chemometric approach for both process optimization and evaluation of different factors for the removal of target pollutants from wastewater. This review provides a thorough examination of notable scholarly works that focus on the use of the RSM in EC for the purpose of wastewater treatment. Furthermore, the current advancements in implementing the RSM approach not only for standalone EC processes but also for the case are described where it is being practiced as a part in the integrating system for wastewater treatment.
