  • 摘要: 以松果为原料，利用ZnCl2活化法和FeCl3改性剂进行活性炭的制备和改性，测定了松果活性炭的比表面积，并研究其对甲基橙染料的吸附性能。结果表明：改性后的松果活性炭比表面积达到681 m2·g-1，并以中孔为主，有利于大分子有机染料的吸附；当松果活性炭的投加量为0.3 g·L-1、吸附30 min、甲基橙初始浓度100 mg·L-1、pH=7以及25℃温度条件下，吸附效果最佳，甲基橙去除率高达99.41%；Langmuir模型比Freundlich模型能更好地描述甲基橙染料的吸附行为，说明吸附以表面单层覆盖为主；吸附动力学符合Lagergren准二级动力学方程，R2大于0.999。可为松果的开发利用和制备低成本、高吸附性的吸附剂提供参考。
    Abstract: In this paper, activated carbon(AC) was prepared from pinecone using ZnCl2 as the activator and FeCl3 as the modifier. The specific surface area of the AC was measured, the adsorption of dyes (methyl orange) on the modified AC was investigated, and the adsorption behavior was described in terms of adsorption isotherms. Results showed that the modified AC had a specific surface area of 681 m2·g-1 and possessed large mesopore volume, which facilitated the adsorption of organic dye molecules. The adsorption of methyl orange was the best when the dosage of modified AC was 0.3 g·L-1, the initial concentration of methyl orange was 200 mg·L-1, and the solution pH was 7, and the treatment was continued for 20 min at 25℃, and the decolorization rate of methyl orange could reach 99.41%. Compared with the Freundlich model, the adsorption data was better fitted by the Langmiur model, indicating monolayer coverage on the carbons and the adsorption of dyes could be described by the Lagergren pseudo-second-order kinetic equation, all R2 exceeding 0.999. This study may serve as a reference for the development and utilization of pinecone and for the preparation of low-cost, high-adsorption adsorbents.
