in the electrochemical coating process, deposition potential,deposition time, the amount of monomers and modified carbon nanotubes doping level should be evaluated for their influence on the extraction efficiency of PAHs.
the copolymerization process was based on the use of an aqueous well dispered suspension of modified CNTs (0.2 wt) containing 0.05 mol oPD and 0.05 mol oT monomers. the sorbent was directly synthesized on the surface of the stainless steel wire by applying a constant deposition potential ranging from 0.8 to 1.8 v for 1500s. clearly, the deposition potential of 1.5 v versus Ag/AgCL WAS found as the optimum value.
