“…Inexpensive adsorbents are those with a high abundance, availability, and low preparation cost. These adsorbents mainly include sawdust, Guar gum, clay, activated carbon, and clinoptilolite zeolite (CZ), which effectively absorb dyes and heavy metals 20 – 24 . CZ has a 3D structure whose typical molecular structure is Na 6 [(AlO 2 ) 6 (SiO 2 ) 30 ]·24 H 2 O. CZ is highly beneficial for practical applications due to its pores, high thermal resistance, and chemically neutral base structure.…”

The present study aimed to remove crystal violet (CV), malachite green (MG), Cd(II), and Pb(II) from an aqueous solution using clinoptilolite zeolite (CZ) as an adsorbent. Response surface methodology (RSM) based on central composite design (CCD) was used to analyze and optimize the process parameters, such as pH, analyte concentration, adsorbent amount, and sonication time. Quadratic models with the coefficient of determination (R2) of 0.99 (p < 0.0001) were compared statistically. The results revealed that the selected models have good precision and a good agreement between the predicted and experimental data. The maximum removal of contaminants was achieved under optimum conditions of pH = 6, sonication time of 22 min, the adsorbent amount of 0.19 g, and analyte concentration of 10 mg L−1. The reusability test of the adsorbent showed that the CZ adsorbent could be used 5 times in water and wastewater treatment processes. According to the results of interference studies, the presence of different ions, even at high concentrations, does not interfere with the removal of contaminants. Applying the CZ adsorbent on environmental water samples revealed that CZ adsorbent could remove CV, MG, Cd(II), and Pb(II) in the range of 84.54% to 99.38% and contaminants present in industrial effluents. As a result, the optimized method in this study can be widely used with high efficiency for removing CV, MG, Cd(II), and Pb(II) from water and wastewater samples.

“…The figure illustrates that the powder XRD patterns of biomass showed a broad diffraction peak at two theta positions of 23 • , which demonstrates that the biomass sample is amorphous with small crystallinity. The amorphous nature of biomass is also supported by our previous studies carried out on the seeds of Datura metel [40]. The synthesis of AC from the obtained Trachycarpus fortunei seeds showed a crystalline structure.…”

The removal of dyes from industrial effluents is one of the most important industrial processes that is currently on academic demand. In this project, for the first time, Trachycarpus fortunei seeds are used as biosources for the synthesis of activated carbon (AC) using physical as well as acid–base chemical methods. The synthesized AC was initially characterized by different instrumental techniques, such as FTIR, BET isotherm, SEM, EDX and XRD. Then, the prepared activated carbon was used as an economical adsorbent for the removal of xylenol orange and thymol blue from an aqueous solution. Furthermore, the effect of different parameters, i.e., concentration of dye, contact time, pH, adsorbent amount, temperature, adsorbent size and agitation speed, were investigated in batch experiments at room temperature. The analysis of different techniques concluded that the pyrolysis method created a significant change in the chemical composition of the prepared AC and the acid-treated AC offered a high carbon/oxygen composite, which is graphitic in nature. The removal of both dyes (xylenol orange and thymol blue) was increased with the increase in the dye’s initial concentration. Isothermal data suggested that the adsorption of both dyes follows the Langmuir model compared to the Freundlich model. The equilibrium time for AC biomass to achieve the removal of xylenol orange and thymol blue dyes was determined to be 60 min, and the kinetic data suggested that the adsorption of both dyes obeyed the pseudo-second order model. The optimal pH for thymol blue adsorption was pH 6, while it was pH 2 for xylenol orange. The adsorption of both dyes increased with the increase in the temperature. The influence of the adsorbent amount indicated that the adsorption capacity (mg/g) of both dyes reduced with the rise in the adsorbent amount. Thus, the current study suggests that AC prepared by an acid treatment from Trachycarpus fortunei seeds is a good, alternative, cost effective, and eco-friendly adsorbent for the effective removal of dyes from polluted water.

“…Adsorption is one of the main applications of activated carbons because they make it possible to concentrate pollutants for later disposal. [6][7][8][9][10][11][12] In this article, we use palm oil waste to prepare activated carbons and analyze their potential application as Methylene Blue (MB) adsorbents based on their kinetic behavior and adsorption isotherms. Kinetic data for the adsorption process were found to fit to the pseudo-second-order kinetic model.…”

Aiming to add value to the ever-increasing amount of residues from the palm oil industry around the world, lignocellulosic waste from palm oil (Lp) was used in this study to prepare activated carbons (ACLp) by chemical activation using KOH at 700 °C developing an area up to 1683 m 2 g À 1 , this value was higher than that obtained for a sample of activated carbon prepared from commercial lignin (ACLc) of 588 m 2 g À 1 . The activated carbons were deeply characterized by different techniques as SEM, FTIR, TGA, and nitrogen adsorption isotherms. The adsorption capacity of the obtained activated carbons for methylene blue (MB) was assessed. According to the results of the mathematical fits performed to the adsorption process, the adsorption isotherm showed a better fit to the Langmuir-Freundlich model, with a maximum adsorption capacity of 188 and 51 mg g À 1 for ACLp and ACLc respectively. In addition, its adsorption kinetics was found to fit better to the pseudo-second-order kinetic model. Additionally, the ΔG 0 value was lower for ACLp (À 31 KJ mol À 1 ) than for ACLc (À 26 KJ mol À 1 ) showing that the interaction between the MB and ACLp is more favorable.
