In situ mercury film coated graphite pencil electrode (MF/GPE) was applied for determination of lomustine (LMT).
Parameters optimization for preparation of MF/GPE was examined.
The modified electrode showed high sensitivity in wide linear range and low detection limit.
The electrochemical parameters for the reduction of LMT at the MF/GPE were calculated.
The modified electrode was successfully applied for determination of LMT in human fluids.
