PREPARATION OF ADSORPTION MATERIAL FOR OIL-WATER SEPARATION FROM MODIFIED ABANDONED MASKS

  • 摘要: 近年来,废弃口罩数量巨大,焚烧、填埋等处置方式存在资源浪费和潜在环境风险,寻求一种环保、经济、可行的处置方式成为迫切需要。采用氢氧化钠、正硅酸乙酯和十八烷基三氯硅烷对废弃口罩进行疏水改性,通过扫描电镜(SEM)、红外光谱分析仪(ATR-FTIR)、接触角测量等分析,结果表明改性后口罩表面形成完整、均匀的疏水包覆层,水接触角达到141.1°。改性后的口罩对润滑油、大豆油的吸附量分别达到28.52,26.84 g/g,且经10次吸油-解吸循环利用,吸油性能仍保持稳定。该研究为废弃口罩的资源化利用提供了一种新途径,具有较好的应用前景。
