This study is related to the electrochemical determination of carboplatinum. The main problem associated with the electrochemical examination of this compound is its slow rate of reaction. Therefore the main goal of this study was to find the appropriate electrocatalysis which may accelerate the rate of reaction. The compound was examined by the use of modified carbon paste (MCPE), modified glassy carbon (MGCE) and platinized platinum (Ptz/Pt) electrodes. Among these, MCPE electrode showed to be the most effective electrocatalyst. The results indicated that the compound could be quantitatively determined in the concentration range of 9.0xl0'5 and 8.0 <10 M with Ptz/Pt and 9.0x10'5 and 9.0*1 O'4 M with modified carbon paste electrodes.
