摘要：近年来,水体中悬浮的超细固体颗粒物等纳米污染引起了人们的广泛关注,然而传统过滤和絮凝沉降等技术去除超细悬浮固体颗粒物的能力有限.本文开发了一种MoS_(2)/氧化石墨烯海绵(SMG-S),可以实现对超细固体颗粒物的高效去除.SMG-S表面经过简单的化学吸附CaCO_(3)改性后,可增强其表面电正性,实现对电负性超细固体颗粒物(~500 nm)的选择性去除.较强的化学作用力是SMG-S吸附固体颗粒物的关键,而物理吸附作用则决定了海绵的吸附容量,两者共同作用使得总悬浮固体颗粒物(TSS)的去除率增加了1206倍,且饱和吸附量可达11.5 g/g.SMG-S还可引发助催化芬顿反应降解磺胺嘧啶等有机污染物(降解率>90%),并实现对重金属离子(去除率>84%)和TSS(去除率>90%)的同步去除.此外,SMG-S类芬顿体系可高效处理皂化油废水,使其化学需氧量和TSS分别从8800和4600 mg/L减小到800和120 mg/L,这说明SMG-S具有处理实际工业废水的潜在应用前景.
Most nanopollution is caused by solid particles in the ground and soil[1,2].These particles carry other refractory pollutants,such as heavy metal ions,microbial molecules,and microplastics[3].In particular,ultrafine suspended solids(approximately 0.1 to 100 lm[4,5])can be deposited in the lungs[6]and can directly enter the blood circulation,thereby causing irreversible damage to the human body[7,8].
