多次标准加入法是应用离子选择电极(ISE)分析中准确度较高的一种方法。特别是在电极斜率未知,或在标准液与待测液中不一致时,更有其独到之处。计算机技术的发展,使标准加入法数据处理的研究不断深入,进一步促进了该方法的应用。对于二次标准加入法,已有人通过推导误差公式和用Monte Carlo方法模拟随机误差的传播,考察 Multiple standard additions are one of the more accurate methods for applying ion selective electrode (ISE) analysis. Especially in the electrode slope is unknown, or in the standard solution and the test solution is inconsistent, even more unique. With the development of computer technology, the research of data processing by standard joining method has been further deepened and the application of this method has been further promoted. For the quadratic standard addition method, it has been investigated by deriving the error formula and simulating the propagation of random errors with the Monte Carlo method
