Kinetic, isothermal and thermodynamic studies for the oil spills removal process have been conducted by Chitosan and novel amphiphilic Chitosan-g-Octanal Schiff base adsorbents developed by click chemistry and evaluated successfully in the removal of heavy crude oil spills. Chitosan was first prepared from wastes of marine shrimp shells, and then Chitosan and Chitosan-g-Octanal Schiff base adsorbents were synthesized and verified their structures, thermal stability and their morphological changes using FT-IR spectroscopy, TGA and SEM. The oil adsorption percentages (%) using heavy crude oil were 96.41% for the Chitosan-g-Octanal Schiff base adsorbent compared to 64.99% for native Chitosan counterpart. High rate of adsorption was observed where 40% of oil adsorbed within 15 min only using the Chitosan-g-Octanal Schiff base adsorbent compared to 90 min for native Chitosan adsorbent. The adsorption process followed the pseudo-second order model, and the equilibrium data were sufficiently fitted with the Langmuir model with a maximum adsorption capacity 30.30 g/g at 25 °C. Thermodynamic parameters computed from Van’t Hoff plot confirmed the process to be endothermic, favorable and spontaneous.

壳聚糖和通过点击化学开发的新型两亲壳聚糖-g-辛醛席夫碱吸附剂对溢油清除过程进行了动力学、等温和热力学研究，并在清除重质原油泄漏中成功进行了评估。首先从海虾壳废料中制备壳聚糖，然后合成壳聚糖和壳聚糖-g-辛醛席夫碱吸附剂，并利用红外光谱、热重分析和扫描电镜验证了它们的结构、热稳定性和形态变化。对于壳聚糖-g-辛醛席夫碱吸附剂，使用重质原油的油吸附百分比 (%) 为 96.41%，而天然壳聚糖对应物为 64.99%。观察到高吸附率，其中 40% 的油仅使用壳聚糖-g-辛醛席夫碱吸附剂在 15 分钟内吸附，而天然壳聚糖吸附剂为 90 分钟。吸附过程遵循准二级模型，平衡数据与Langmuir模型充分拟合，25℃时最大吸附量为30.30 g/g。从 Van't Hoff 图计算的热力学参数证实该过程是吸热的、有利的和自发的。
