Abstract:P-nitroaniline (PNA) is an aniline compound with high toxicity and can cause serious harm to aquatic animals and plants. Multiwalled carbon nanotubes (MWCNTs) are a multifunctional carbon-based material that can be applied in energy storage and biochemistry applications and semiconductors as well as for various environmental purposes. In the present study, MWCNTs (CO2–MWCNTs and KOH–MWCNTs) were obtained through CO2 and KOH activation. ACID–MWCNTs were obtained through surface treatment with an H2SO4–HNO3 mixt… Show more
