柚子皮制备多孔碳材料处理聚氯乙烯微塑料废水实验研究

柚子皮是福建漳州常见的农业废弃物,作为垃圾处理对环境造成一定压力,急需开展资源化利用。本论文以柚子皮为原料,碱活化和高温碳化制备多孔碳材料,并将其应用于聚氯乙烯微塑料的处理。实验结果表明,制备的多孔碳材料对聚氯乙烯微塑料具有较好的吸附处理效果。聚氯乙烯微塑料去除率随着吸附时间和多孔碳材料投加量的增加而逐渐增大。多孔柚子皮碳材料适宜在弱酸或弱碱性条件下处理聚氯乙烯微塑料废水。这为柚子皮资源化利用提供了新方向和技术。

Experimental Study on the Treatment of Polyvinyl Chloride Microplastics Wastewater with Porous Carbon Material Prepared from Pomelo Peel

Pomelo peel is a common agricultural waste in Zhangzhou, Fujian Province. As garbage disposal, it puts a certain pressure on the environment and urgently needs to be used as a resource. Pomelo peel was used as raw material to prepare porous carbon materials by alkali activation and high temperature carbonization, and then applied to the treatment of polyvinyl chloride (PVC) microplastics in this study. The experimental results shown that the porous carbon material had good adsorption effect on PVC microplastics. The removal rate of PVC microplastics increased with the increase of adsorption time and dosage of porous carbon material. The porous carbon materials of pomelo peel was suitable for the treatment of PVC microplastic wastewater under weak acid or weak alkali conditions. These would provide a new direction and technology for the resource utilization of pomelo peel.
