摘要	A graphite electrode (GE) was modified in a 2.3 mol/L H2SO4 solution using GE as a working electrode, Pt as a counter electrode andsaturatedcalomelelectrode (SCE) as a reference electrodeby a galvanic method under a constant current. Results showed thatafter the GE was optimally modified at a current of 200 mAfor 300 s and -120 mA for 100 s for 6 cycles, it had a porous, rough and three-dimensional active layer with a pseudo capacitance of 2.08 F/cm(2). The modified GE had a much lower resistance and higher sweep rate than the unmodified one.
