This study deals with the synthesis of a new Organo-Kaolinite material containing sulfonate groups by grafting an anionic surfactant, sodium dodecylbenzene (SDBS), onto surface Algerian Kaolinite DD3 for use in removal textile dye (Methylene Blue, MB). The investigation kinetics adsorption process is accordance pseudo-second-order model, and isotherm data are Langmuir model two materials, SDBS-DD3. A comparative analysis between SDBS-DD3 showed that despite decrease BET area after modification (from 68 m2/g to 46 m2/g), amount absorbed was 93.8 ± 0.9 mg/g compared 44.5 0.2 DD3. Adsorption experiments on real wastewater effluents significant reduction effluent pollutants. In fact, during first 2 min experiment, chemical oxygen demand (COD) reduced 94%. More specifically, COD value untreated effluent, which initially 304 mg/L, 29 mg/L.

Adsorption Performance and Mechanistic Pathways of Raw Powdered Pine Cone Toward the Removal of Dye and Cr(VI)

International Journal of Chemical Kinetics, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 13, 2025

ABSTRACT This work aims to valorize pine cones powder (PCP), an agricultural waste, as a bioadsorbent for the removal of cationic dye, Rhodamine B (RhB), and hexavalent chromium Cr(VI) from aqueous solution. The adsorbent was characterized by scanning electron microscopy (SEM), Fourier‐transformed infrared (FTIR), X‐ray diffractometer (XRD) spectroscopy. Adsorption studies were carried out in batch mode under different operating parameters like initial solution pH (2–11), dosage (0.025–0.6 g), contaminant concentration (20–100 mg/L), temperature (283–328K), contact time (0–120 min), ionic strength (NaCl, MgCl 2 , CuSO 4 Na SO FeCl 3 ). optimum conditions adsorption were; ([Cr(VI)] = 30 mg/L, 2, dose 1.5 g/L, T 25°C), RhB: ([RhB] 4.6, 25°C). Under these conditions, maximum capacities reached 19.861 6.565 mg/g, RhB, respectively. inhibiting effect studied salts on RhB dye metal ion is follows: > NaCl. Freundlich isotherm described best Cr (VI) onto PCP, since it gave highest R values (R ≥ 0.983) associated with lowest error (χ RMSE, Δq). calculated Dubinin–Radushkevich mean energy (E) less than 8 kJ/mol. It 3.391 kJ/mol 2.310 sorption, respectively, confirming physical character PCP sorbent. Experimental data fitted well pseudo‐second‐order kinetic model 0.997). According thermodynamic analysis, retention followed physisorption, endothermic, spontaneous process at all temperatures Cr(VI), higher dye. These results suggest that raw may be envisaged promising biosorbent water remediation without need costly heat activation processes cheap sustainable process.
