This study optimizes CO2 adsorption using hydrochar from de-oiled flaxseed (FDOP), a waste byproduct of the oil extraction industry, through hydrothermal carbonization (HTC). The aim is to enhance capture sustainably and cost-effectively. Using Response Surface Methodology (RSM), in optimal conditions achieved 1153.26 mg/g capacity under 215.15 °C synthesis temperature, 3.05 h time, 0.99 M acid concentration, 8.997 bar pressure, 25.07 temperature. Statistical analysis (F-value: 44.48, R²: 0.9705) confirmed strong model reliability.

Lithium is a strategic element for energy storage. Extraction from surface water promising method the purification of lithium. Synthetic model brines containing lithium and sodium ions were prepared extraction experiments. A hydrophobic deep eutectic solvent (HDES) was synthesized using tetrabutylammonium chloride (TBAC) as hydrogen bond acceptor (HBA) decanoic acid (DA) donor (HBD). Trioctylphosphine oxide (TOPO) chosen coextractant. Fourier transform infrared (FT-IR) 1H NMR analyses confirmed physical interactions between HBD HBA. Response methodology used to optimize operational parameters percentage selectivity. The organic phase TBAC(1)/DA(2) 10 wt % TOPO at T = 23.0 °C pH 10.4 demonstrated highest performance. optimized point yielded selectivity 4.41 an efficiency 48.57% one stage extraction. ion exchange reaction in (DES) by FT-IR spectroscopy. Five regeneration cycles revealed that remained stable after third cycle. brine with same composition Iran's sources 51.63% compared those sodium, potassium, magnesium, calcium ions, which 9.97, 3.11, 4.38, 2.29%, respectively. HDES this study cost-effective biodegradable other HDESs reported literature.
