【摘要】 本文在离子选择电极的线性响应范围内使用多次标准加入法,分别测定水样品中的碘离子。在线性响应范围内,多次标准加入法的测定已提供了足够多的数据。基于非线性方程组的最小二乘法拟合,用迭代法求解;在电脑预先编好程序,代入电池电动势的测定结果,可以迅速计算出电极的响应斜率和样品溶液的碘离子的浓度。更多还原

【Abstract】 The multiple standard addition method has been used in determinatiom of iodine ion in ISE linear response range. Assayin multiple standard addition has provided enough data for resolution of nonlinear equations.Through least squares and iterationmethod, the response slope of electrode and iodine ion concentration of sample solution could be calculated rapidly by computer.更多还原
