摘要
主要以爆米花为原料,通过低温碳化、活化、高温碳化及化学改性相结合的方法,成功将普通爆米花转化为具有高比表面积和多孔结构的碳材料,展现出优异的吸附性能。通过实验,对实验结果进行分析和讨论,最终确定了最佳工艺条件为:低温碳化温度300℃、碳化时间3 h;活化剂KOH浓度为1.5 mol/L;高温碳化温度900℃,碳化时间3 h。在此实验条件下,制得的改性爆米花多孔碳对酸性湖蓝A染液的去除率可达到93%,去除效果显著。本研究不仅提供了一种经济高效的废弃物资源化策略,还建立了食品废弃物衍生吸附剂的结构-活性关系,为工业废水处理提供了新思路。
In this paper,using popcorn as raw material,through the combination of low temperature carbonization,activation,high temperature carbonization and chemical modification,ordinary popcorn was successfully transformed into carbon material with high specific surface area and porous structure,showing excellent adsorption properties.Through the experiment,the experimental results were analyzed and discussed,and the optimum process conditions were determined as follows:low temperature carbonization temperature 300℃,carbonization time 3 h;The concentration of activator KOH was 1.5 mol/L.High temperature carbonization temperature 900℃,carbonization time 3 h.Under the experimental conditions,the removal rate of modified popcorn porous carbon to acid lake blue A dye can reach 93%,and the removal effect is remarkable.This study not only provides an economical and efficient strategy for waste resource utilization,but also establishes the structure-activity relationship of food waste-derived adsorbents,offering new insights for industrial wastewater treatment.
