A surface modified electrode and a method of preparing the surface modified electrode are provided. The surface modified electrode includes a glassy carbon electrode and a coating of a compound of formula I disposed on the glassy carbon electrode. The present disclosure also relates to a method of preparing the surface modified electrode. The method includes depositing a slurry of the compound of Formula I on the glassy carbon electrode to form a film and coating a polymer matrix on the film to obtain the surface modified electrode. The present disclosure also relates to a method of preparing the compound of Formula I. The method includes condensing 4-bromobenzaldehyde (4-BBD) and 4-methyl-benzenesulphonylhydrazine (4-MBSH), to obtain a first mixture and precipitating the first mixture to obtain the compound of Formula I. The surface modified electrode is used in an electrochemical sensor for the detection of metal ions.
