摘　　要：讨论了用离子选择性电极法测定Br-时,不同浓度等级Cl-干扰状况及溴电极的电位响应能力变化情况。同时提出了应用Matlab建立线性回归方程测定Br-的方法,回归系数平方值R2 =1,回归方程与实验观测数据拟合理想。Ion selective electrode has been used to measure the concentration of bromide ion. The response of bromide electrode potential was detected under the disturbance of chloride ion as coexist ion at various concentration levels. We propose a method to create linear regression equation with Matlab,the equation could be use to measure the concentration of bromide ion. The equation’s square regression coefficient is one and fitted well with experimental datas.
