Important characteristics are the surface chemistry and purity of CNT.For MWCNT synthesized using a metal catalyst, the toxicity may be the combined effect of the MWCNT themselves and an oxidative stress response to the residual metal catalyst[] typically amounting to less than about 5 wt.%.All MWCNT have a tubular structure with a high aspect ratio and between 2 and 30 concentric cylinders with outer diameters commonly between 30 and 50 nm.The small size and the high surface area define the chemical reactivity of CNT and induce changes in permeability or conductivity of biological membranes[].Triclocarban is a high-production volume chemical that is widely used as an antimicrobial compound and is known for its toxicity, hydrophobicity, endocrine disruption, bioaccumulation potential, and environmental persistence.

Nanotechnology has initiated different types of nanomaterials to be used in water technology in recent years that can have promising outcomes.To date, only a few reports about studies on toxic effects of carbon nanotubes (CNT) are available, and their results are often controversial.
