摘　　要：利用微机在电位溶出理论滴定曲线上叠加偶然误差模拟实际滴定曲线，比较了从滴定曲线求水中痕量金属有机络合参数的两种数学处理方法；并对滴定程序进行了优化。The effect of random analytical errors on the determination of complexation paramters in natural water by Potentiometric Stripping Titration Analysis(PSTA) is studied by means of computer simulation.Two graphical treatment,the Berg-Ruzic and Scatchard plots,for the evalution fromtitration data are compared. Effect of the spacing titrant increments on the determination of complexation parameters is examined and the titration procedure is optimized.
