摘要

This study investigates the enhancement of oil sorption efficiency using acetylated chicken feather sorbents. Acetylation, a chemical modification process, was optimized to improve the sorption capacity of chicken feather sorbents for oil spill cleanup applications. Experimental data on the acetylation of chicken feathers revealed that the optimal conditions for acetylation include a 3% n-bromosuccinamide catalyst concentration, a reaction temperature of 40 ℃, and a reaction duration of 90 min. Functional group analysis revealed that the acetylation process led to a decrease in the intensities of the hydroxyl functional group in the chicken feather. The acetylated and unacetylated samples gave maximum adsorption capacities of 3.394 g/g and 3.247 g/g at 50 min, respectively. The uptake of oil by the unacetylated and acetylated chicken feathers was observed to follow the pseudo-first-order model. These findings highlight the importance of optimizing the acetylation process to maximize the oil sorption efficiency of chicken feather sorbents, thereby contributing to more effective and sustainable oil spill remediation strategies.
