Summary: The mechanism of methylene blue adsorption on palm kernel shell-derived activated carbon was investigated. The adsorption capacity of methylene blue decreased with lower initial dye concentrations, with 100 ppm leading to approximately 10 mg/g and 50 ppm, 20 ppm, and 5 ppm resulting in lower adsorption capacities. The adsorption process involved diffusion from the bulk solution to the activated carbon via a bounding film, occupying multiple classes of active sites.

Summary: The ability of novel carbon microspheres (CMs) derived from date palm biomass using a hydrothermal carbonization process and activated using phosphoric acid to remove methylene blue dye was investigated in this study. Three types of palm-based wastes were converted to CMs via the hydrothermal carbonization process and then activated using phosphoric acid. Analysis methods such as SEM, CHNS, FTIR, and BET were used to study the CMs samples before and after activation. The results showed high BET surface areas after activation, with good adsorption capacity for methylene blue dye.

Summary: In this study, a dynamic model was used to simulate and validate the adsorption of methylene blue (MB) dye by jengkol peel-based activated carbon (JPAC) in aqueous solution. The results showed that JPAC synthesized under microwave activation conditions of 400 Watt and 4 minutes achieved favorable properties for MB dye removal, with a high BET surface area and pore volume. The adsorption capacity of MB on JPAC increased as the initial concentration of MB dye increased. The calculated R-2 values indicated a good fit between the model and experimental data, and the mass transfer coefficient decreased with an increase in MB dye initial concentration.

Summary: Cellulose hydrogels were fabricated using LiCl/dimethylacetamide as a new method and investigated for their ability to remove DB86 dye from water. The hydrogel was characterized by FTIR, XRD, SEM, and TGA analyses. The optimum pH for dye absorption was found to be 2, and the Temkin model best fit the absorption results of the hydrogel. Kinetic absorption studies showed that the pseudo-second-order model had the highest R-2 value, indicating strong control over the absorption rate. These findings suggest that cellulose hydrogels have potential for DB86 dye removal from wastewater.

Summary: This study conducted intermediate pyrolysis on desert date shells for the first time and demonstrated their potential as a biomass feedstock for producing high-quality bio-oil and biochar. Fourier transform infrared spectroscopy (FTIR), elemental analysis, and gas chromatography-mass spectrometry (GC-MS) were used to analyze the composition of the bio-oil. The results showed that the bio-oil had a diverse composition rich in oxygenated compounds such as acids, phenolics, and benzene derivatives. The ultimate analysis revealed a higher carbon content and lower oxygen content in the bio-oil compared to the desert date shell. The findings suggest that desert date shells can be an attractive feedstock for producing valuable biomaterials.

Summary: In this study, mixture activated carbon (MAC) was developed from a mixture of date palm wastes through hydrothermal carbonization and microwave-assisted H3PO4 activation. MAC showed mesoporous structure and negatively charged surface with various functional groups. The adsorption capacity of MAC for removing RBBR increased with initial concentration and achieved the maximum at pH 3 and 30 degrees C. Langmuir isotherm and pseudo-first-order kinetic models were the best fit for describing the RBBR-MAC adsorption system. The adsorption process was exothermic, increased randomness at the liquid-solid interface, and controlled by physisorption.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
