膜蒸馏技术对于非挥发性物质具有100%的理论截留率,但对于挥发性物质的截留效果不佳。本研究使用光热膜蒸馏技术,利用光能对膜表面进行原位加热,改善温差极化问题,提高水通量,降低苯酚/水透过比值.本工作通过喷涂法在聚四氟乙烯(PTFE)基膜上制备了碳纳米管(CNTs)复合膜.膜表面CNTs层赋予了复合膜优异的光吸收和光热转换性能,在全光谱范围内光吸收率可达90.64%.在1个太阳光强度下,膜表面温度可上升至(61±1)℃.在使用200 mg/L苯酚、3.5%(质量分数)NaCl溶液在35℃下作为进料液并施加1个太阳光辐射的光热膜蒸馏系统中,膜通量提高了34.4%,太阳能利用率为33.1%,同时盐的截留率始终大于99.9%.光热膜蒸馏对于高盐苯酚溶液中苯酚的分离效果相比传统膜蒸馏有明显提高:在进料液苯酚浓度为200 mg/L的条件下,施加1个太阳光强度后苯酚/水的透过比降低了35.2%.
