“…1). As supported with reference (Ramirez et al 2021),CaCO3 and most of the P content was still forming organic structures and that Ca was in the form of CaCO3 which could effectively increase the crystallinity of the biochar that have a remarkable role in Cr(VI) adsorption (Suryawanshi et al 2023). An increase in disorder of the graphitic sheets of the KOH-WHL-AC enhances the porosity and internal surface area.…”

KOH-Activated carbon derived from Water Hyacinth (KOH-WHL-AC) was prepared and coated with Polyaniline-Polypyrrole (PANI/PPY) copolymer for the removal of hexavalent chromium (Cr(VI)) from wastewater. The prepared material was characterized by FT-IR and XRD. The effect of pH, contact time, dosage, and initial Cr(VI) concentrations were optimized using batch adsorption experiment. The adsorption kinetics was found to fit better to pseudo-second-order than the pseudo-first order model. Langmuir and Freundlich isotherm models were analyzed using linear fitting. It was found that the Langmuir adsorption model gives the best fit indicating that the monolayer adsorption of Cr(VI) on the KOH-WHL-AC. The highest adsorption capacity of 409.83 mg/g was achieved at pH 1.0, and equilibrium was achieved within 420 min. The reuse efficiency of the synthesized material was also found to be greater than 54% for five consecutive cycles. Thermodynamic studies have also been carried out and the adsorption was found to be spontaneous and endothermic

“…The presence of carbonyl groups suggests the existence of aldehydes, ketones, or carboxylic acids on the surface of the activated carbon. These functional groups can enhance the adsorption capacity and affinity towards certain organic pollutants, including dyes (Albalasmeh et al, 2020;Pandey et al, 2022;Shrestha et al, 2019), while the peak observed at approximately 2000 cm -1 can be attributed to the presence of lignin (Suryawanshi et al, 2023).…”

“…The FTIR analysis of the activated carbon provides valuable information about the presence of functional groups that contribute to its adsorption capabilities. The functional groups present contribute to the diverse interactions between the adsorbent and the dye molecules, including hydrogen bonding, π-π interactions, and van der Waals forces (Suryawanshi et al, 2023). The CCD employed five levels for each factor, ranging from -α to +α (Table 1).…”

This study focuses on the optimization of methylene blue (MB) adsorption onto activated carbon derived from pineapple peel waste (ACPPW) using response surface methodology (RSM). The activated carbon was synthesized via a chemical activation method and characterized using FTIR spectroscopy. The adsorption process was optimized by investigating the effects of three key parameters: adsorbent dosage, initial dye concentration, and contact time. A Central Composite Design (CCD) with 20 runs was employed, and ANOVA was performed to determine the significance of each parameter. The central composite design (CCD) was employed to determine the effect of three independent variables, namely adsorbent dosage (X1), initial MB concentration (X2), and contact time (X3), on the response variable, MB removal efficiency (Y). The optimal conditions for achieving a high adsorption capacity of 98.19 % for methylene blue dye were determined to be an adsorbent dosage of 400 mg/L, an initial dye concentration of 15 mg/L, and a contact time of 12 minutes. The regression equation achieved a high R2 value of 0.9883, indicating a good fit for the experimental data and the model's reliability. These findings provide valuable insights into efficiently utilizing pineapple peel waste as a sustainable source for producing activated carbon with excellent adsorption capabilities for dye removal, thus contributing to environmental sustainability and waste management efforts.

“…Screening designs (Plackett-Burman design (PBD)) were used to identify the most important production factors from a large number of factors (Suryawanshi et al, 2021). In the present study, the pyrolysis and adsorption processes (pyrolysis yield (Y 1 ), production cost (Y 2 ), adsorption efficiency for PO 4 3− -P (Y 3 ) or NH 4…”
