The electrochemical behavior of dipyrone was studied on montmorillonite modified electrode by cyclic voltammetry.The result indicated that the process was controlled by diffusion. Determination parameters were optimized and the correlation between peak current and the concentration was studied by square wave stripping voltammetry (SWSV). A good linearity between the peak current and concentration of dipyrone in the range of 2.0×10~(-6) mol·L~(-1)～6.0×10~(-5) mol·L~(-1) was found with a linear equation of I_(pa)(μA)=-0.07784-15443.54011c(μmol·L~(-1)) and a correlative coefficient of -0.9993. The detection limit was 1.12×10~(-6) mol·L~(-1). This method can be used for the determination of dipyrone in real samples.
