“…e models of these responses were both significant due to Prob > F value for DDT removal and CSAC's yield were <0.0001 and 0.0042, respectively. Lack of fit was observed to be insignificant for both responses studied, thus concluding that variables used had a notable effect on the responses and the models fitted the experimental data nicely [20].…”

“…Based on its ability to adsorb a wide range of pollutants, AC is also best known as a universal adsorbent. Several works done by researchers proved that AC is extremely versatile in removing pollutants such as cationic dyes [14,15], anionic dyes [16,17], heavy metals [18], phenolic compound [19], antibiotic [20], painkiller [21], carbon dioxide, CO 2 gas [22], hydrogen sulfide, H 2 S gas [23], and many others. Nevertheless, the application of AC is limited by the expensive cost of the precursors or starting materials.…”

This research aims to optimize preparation conditions of coconut-shell-based activated carbon (CSAC) and to evaluate its adsorption performance in removing POP of dichlorodiphenyltrichloroethane (DDT). The CSAC was prepared by activating the coconut shell via single-stage microwave heating under carbon dioxide, CO2 flow. The total pore volume, BET surface area, and average pore diameter of CSAC were 0.420 cm3/g, 625.61 m2/g, and 4.55 nm, respectively. The surface of CSAC was negatively charged shown by the zeta potential study. Response surface methodology (RSM) revealed that the optimum preparation conditions in preparing CSAC were 502 W and 6 min for radiation power and radiation time, respectively, which corresponded to 84.83% of DDT removal and 37.91% of CSAC’s yield. Adsorption uptakes of DDT were found to increase with an increase in their initial concentration. Isotherm study revealed that DDT-CSAC adsorption system was best described by the Langmuir model with monolayer adsorption capacity, Qm of 14.51 mg/g. The kinetic study confirmed that the pseudo-second-order model fitted well with this adsorption system. In regeneration studies, the adsorption efficiency had slightly dropped from 100% to 83% after 5 cycles. CSAC was found to be economically feasible for commercialization owing to its low production cost and high adsorption capacity.

“…The suspension was injected into the sample tank with a syringe, the zeta potential was measured in the sample tank, and the curve of the zeta potential changing with pH was drawn. When the zeta potential was 0, the corresponding pH was the point of zero charge of the material (pHpzc) (Melliti et al 2021).…”

Copper tailings (CTs) and orthophosphate are major environmental pollutants. CTs cause severe heavy metal pollution, and orthophosphate is one of the primary causes of water body eutrophication. This study aimed to alleviate heavy metal pollution by CTs and the eutrophication of water caused by orthophosphate. To this end, a 50 mg/L orthophosphate was used as a chemically active leaching solution and passed through a CT soil column. The tail water was then collected. Laboratory leaching tests showed that the thermally modified CTs effectively trapped orthophosphate, and the orthophosphate content in the leachate was 0.15 mg/L. After chemical washing, Cu2+, Cd2+, and Zn2+ were tested in the tail water, and the heavy metal ions in the tail water were removed using an advanced treatment technology. After treatment with 20.0 g/L water hyacinth biochar (WHBC), the removal rates (R%) of Cu2+, Cd2+, and Zn2+ were 99.48, 94.94, and 94.84%, respectively. These results demonstrated that this novel scheme for the synergistic purification of CTs and orthophosphate was feasible in the laboratory. This study provides new theoretical guidance and technical support for CT soil heavy metal remediation and water eutrophication treatment.

“…According to literature studies in recent decades, the researchers' interest focused on the finding of cheap adsorbents that may be used as adsorbents for wastewater treatment and to study the effectiveness of these materials to remove pollutants such as removal of methyl orange dye using different agriculture wastes (Dakhil 2016a(Dakhil , 2020). In addition, modern studies focused on preparing activated carbon from agricultural wastes as eco-friendly adsorbents, such as the production of activated carbon prepared from date palm fibers (Dakhil and Ali 2021, Melliti et al 2021 The importance of this work involves highlighting the chemical modification of agricultural wastes (i.e. rice husks) and examining the ability of MRH to remove aniline ions from contaminated water, as well as optimizing the operating factors under batch adsorption technique.…”

The present work is aimed at investigating the capability of chemically modified rice husks (MRH) for the reduction of aniline ions from industrial wastewater. The experiments have been conducted to examine the influence of four operating parameters in the batch adsorption technique. The effect of initial concentrations of aniline (10-100) mg•L -1 , MRH dose (0.1-1) g/100 ml, pH (3-9), and contact time (10-90) min has been studied. The selected range of operating factors was designed using the response surface method to establish a mathematical model that describes the adsorption process. The optimum parameters were 25 mg•L -1 initial concentration of aniline, 0.68 g MRH dose, 6.6 pH, and 70 min contact time. The point of zero charge was found equal to 6.8. The maximum removal efficiency of 84.97% was found under optimum conditions. The consistency of the mathematical model has been examined and the equilibrium results confirmed with the standard adsorption isotherm models, Langmuir and Freundlich, with a high correlation coefficient.
