The carbon-based nanostruct ures [۱], especially single [۲] and m ultiwalled carbon nano tubes (MW CNTs) [۳], h ave been ex tensively studied for their role as solid substrates, mainly d ue to the accessibility o f enormous surface ar ea that can be readily functionalize d [۴]. Thus how treate d surfaces can be used to adsorbed heavy transition metals, which ma y be presen ce in water, waste and etc. The main questio n of this st udy is the investigation of capability of CNTs as filters for adsorption of vanadiu m ions in ind ustrial wastewaters.
