Influence Of Dissolved Organic Matter On Organic Pollutant Removal By Multiwalled Carbon Nanotubes
ENVIRONMENTAL ENGINEERING SCIENCE(2017)
摘要
Influence of dissolved organic matter (DOM) on removal efficiency of phenanthrene and 1-naphthol by multiwalled carbon nanotubes (MWCNTs) was examined. A model DOM, succinic acid, did not reduce removal efficiency of phenanthrene and 1-naphthol by MWCNTs with varying outer diameters (ODs), due to its very low sorption to these sorbents and thus minimal influence on their surface properties. In contrast, humic acid (HA) introduction highly reduced their removal by MWCNTs. Molecular size and sorption strength of tested HAs by a given MWCNT generally followed the order: HA1更多
