▎ 摘　　要

Graphite paste electrodes were modified by addn. of reduced graphene oxide or multi-walled C nanotubes and for comparison C black (2-6% by mass) and studied for their ability to accumulation of p-ClC6H4OH by cyclic voltammetry. The peak current increased with the increasing amt. of nano-modifier added. No essential difference between the reduced graphene oxide and the nanotubes was obsd.
