Preparation of sulfonic acid-based functionalized biochar (PPBC) by modifying discarded pomelo peels through low-temperature sulfonation method and its application in adsorbing iron ions from high-concentration sulfuric acid solutions was investigated. The effects of adsorption time, temperature, stirring speed, initial mass concentration of iron ions and acidity on the adsorption performance of PPBC were examined, and the adsorption and separation mechanism as well as the recycling and regeneration performance were discussed. The results show that under the optimized conditions of sulfuric acid concentration of 0.1 mol/L, temperature of 55 ℃, stirring speed of 200 r/min, initial mass concentration of iron of 1 000 mg/L, and adsorption time of 120 min, the adsorption rate of PPBC for iron ions reaches 98.2%, and the adsorption capacity is 98.2 mg/g. When the initial mass concentration of iron ions is 5 000 mg/L, the adsorption capacity of PPBC for iron ions reaches a maximum of 324.6 mg/g. The adsorption behavior conforms to the Langmuir isothermal adsorption model and the pseudo-second-order kinetic model, and belongs to monolayer chemical adsorption. After five adsorption-desorption cycles, the regeneration rate of PPBC remains at 87.8%. PPBC has excellent structural stability and reusability, which can provide technical references for the treatment of high-acid and high-iron wastewater and the high-value utilization of agricultural waste.

研究了采用低温磺化法改性柚子皮制备磺酸基功能化生物炭（PPBC），并用于吸附高浓度硫酸溶液中铁离子。考察了吸附时间、温度、搅拌转速、铁离子初始质量浓度及酸度对PPBC吸附性能的影响，探讨了吸附与分离机制及循环再生性能。结果表明：在硫酸浓度0.1 mol/L、温度55 ℃、搅拌转速200 r/min、铁离子初始质量浓度1 000 mg/L、吸附时间120 min优化条件下，PPBC对铁离子的吸附率达98.2%，吸附容量为98.2 mg/g；在铁离子初始质量浓度为5 000 mg/L时，PPBC对铁离子的吸附容量达最大值324.6 mg/g；吸附行为符合Langmuir等温吸附模型和准二级动力学模型，属于单分子层化学吸附；经过5次吸附-解吸循环后，PPBC再生率仍保持87.8%。PPBC具有良好的结构稳定性与重复使用性，可为高酸高铁废水的治理及农业废弃物高值化利用提供技术参考。
