A considerable increase in the importance of vanadium globally and its common uses in many manufacturable alloys made it a target for much scientific research interested in extraction and recovery. A solid modified cellulose sorbent (GCIHQ) was prepared by simple grafting of cellulose, then immobilized with hydroxyquinoline, and examined as a sorbent for V(V) ions. FT-IR, TGA, BET, and SEM–EDX investigations were used to characterize the GCIHQ. A higher surface area for the synthesized GCIHQ resin has been recorded (65.8 m²/g) more than the used cellulose (21.7m²/g). Several vanadium sorption parameters using the modified GCIHQ from the sulfate medium were optimized namely contact time, pH, initial vanadium ions concentration, sorbent dose, and sorption temperature. The kinetics results revealed that the sorption of vanadium ions upon the synthesized sorbent followed the pseudo-second-order with R² of > 0.99, which indicated that the sorption mechanism was chemical interaction. The sorption process was studied using Freundlich, Langmuir, Dubinin–Radushkevich, and Temkin isotherm models to describe the adsorbent-adsorbate interaction. The Langmuir model was the most fitting model with the experimental results; the experimental adsorption uptake of 113 mg/g was matched with that of the calculated results. The activation energy (E_a) for adsorption was 12.91 kJ.mol⁻¹, indicating the process is to be chemisorption. Thermodynamic characteristics with ΔH of 13.46 kJ/mol and a ΔS 115.15 J/mol.K revealed the endothermic and spontaneous nature.

钒在全球范围内的重要性显着提高，并在许多可制造合金中普遍使用，使其成为许多对提取和回收感兴趣的科学研究的目标。通过简单的纤维素接枝制备固体改性纤维素吸附剂 (GCIHQ)，然后用羟基喹啉固定，并作为 V(V) 离子的吸附剂进行检测。FT-IR、TGA、BET 和 SEM-EDX 研究用于表征 GCIHQ。已记录到合成的 GCIHQ 树脂的表面积（65.8 m ² /g）高于使用的纤维素（21.7m ^{2 ）}/G）。使用改性 GCIHQ 从硫酸盐介质中吸附钒的几个参数进行了优化，即接触时间、pH、初始钒离子浓度、吸附剂剂量和吸附温度。动力学结果表明，钒离子在合成吸附剂上的吸附遵循准二级吸附，R ² > 0.99，表明吸附机理为化学相互作用。使用 Freundlich、Langmuir、Dubinin-Radushkevich 和 Temkin 等温线模型研究吸附过程，以描述吸附剂-吸附质的相互作用。Langmuir模型是与实验结果最吻合的模型；113 mg/g 的实验吸附量与计算结果相匹配。活化能（E _a) 的吸附量为 12.91 kJ.mol ^-1，表明该过程是化学吸附。ΔH 为 13.46 kJ/mol 和 ΔS 为 115.15 J/mol.K 的热力学特性揭示了吸热和自发性质。
