The present study reported the preparation of solid phases from various available and cheap natural sources represented by activated carbon to remove the polluting dye Congo Red (CR). Activated carbon derived from the leaves of the Consocarpus plant (C/AC) and Ziziphus Spina-Christi plant (Z/AC) and Myrtus plant (M/AC) by chemical activation. The solid phases were diagnosed and examined using FTIR, FESE, and XRD. The results of the study indicated that the best amount for the solid phase was 0.25 g for the three solid phases used against dye, the optimal concentration of the CR was 100 mg L-1, and the optimum acidity function was equal to 5 with a volume of 25 mL, as the optimization experiments indicated that the best flow rate of the eluting solution was equal to 0.5 ml min-1. The elution processes were carried out using several solvents different in polarity and it was found that 8 mL of DMSO achieved the best percentage of recovery (%R). Also, the adsorption capacity based on the optimal conditions that were obtained by applying Langmuir and Freundlich isotherm models, and qmax, according to the Langmuir model, was (21.74, 23.53, 22.17) mg g-1 for (Z/AC), (C/AC), and (M/AC) adsorbents, respectively.

“…The selection, preparation, or synthesis of sorbent in this method is the most critical factor in the success of contaminant removal (Ghorbani et al 2020). An excellent sorbent has characteristics such as non-toxicity, low cost, high sorption capacity, good reusability, and suitable pollutant sorption at a reasonable time (Farrokhzadeh et al 2020). Today, green sorbents are highly regarded for removing pollutants because of their agreement with green chemistry (Bulgariu et al 2019).…”

In the study, an adsorptive removal strategy as a straightforward and fast procedure was developed to remove four aflatoxins, including aflatoxin B1 (AF-B1), aflatoxin B2 (AF-B2), aflatoxin G1 (AF-G1), and aflatoxin G2 (AF-G2). A simple and green sorbent consisting of two components (activated nanobentonite and Fe3O4 nanoparticles) was synthesized based on three steps using acidic treatment, ultrasonic procedure, and chemical precipitation method. The sorbent was characterized by several techniques such as FTIR, FESEM, TEM, XRD and VSM to determine the sorbent structure and morphology. An experimental design based on a central composite design was utilized to optimize factors in the removal of AFs. The optimum values of the factors (pH, sorbent amount, shaking rate) was 6.8, 0.076 g and 160 rpm, respectively. Three models, including pseudo-first-order, pseudo-second-order, and intra-particle diffusion models, were used to investigate the kinetics of the removal process. The removal of AFs using magnetic nanobentonite was fitted with the pseudo-second-order model better than other models with an equilibrium time lower than 30 min. the thermodynamic data show that the adsorption of AFs on the sorbent is a spontaneous and feasible process due to negative values of the Gibbs free energy change (ΔG) at different temperatures. Two models (Langmuir and Freundlich models) were chosen to study the isotherm of the removal procedure, indicating that the Freundlich model describes the results better than the Langmuir model. The maximum adsorption capacity of the sorbent for removing AF-B1, AF-B2, AF-G1, and AF-G2 are 357.14, 400.0, 370.37, and 400.0 mg g− 1, respectively. The sorbent reusability was also evaluated to study the sorbent's ability for the removal of AFs, indicating that the sorbent was used for 5 cycles without a significant reduction in the ability to remove AFs.

“…Polycyclic aromatic hydrocarbons (PAHs) are one of the main groups of global pollutants that are generally formed during different imperfect thermal procedures and human activities [1]. PAHs can contaminate the foodstuffs from the air, soil, and water and also within the preparing, conservation, storage, and cooking procedures [2]. Most of the PAHs are carcinogenic and mutagenic and possess highly toxic impacts on the human organism.…”
