【Abstract】 The mathematical treatment of the ion -selective electrods multi-addi-tion technique by a numerical value method is presented in this paper. The author uses the Newton- Raphson iterating method to obtain the unknown concentration Cx, and uses the least squares method toobtain the condition potential, E0/and the practical slope of the ion-selective electrode S.The advantages of the procedure proposed and other methods prior to it are discussed and compared.更多还原
