近年来,离子选择性电极的多次标准加入法的计算机解已有几种不同的方法被陆续提出。付敏恭等人提出的连续多次标准加入法的计算程序,虽然具有程序结构简单,收敛速度较快等优点,但它要求样品溶液体积和标准溶液加入体积为100:1,各次加入标准溶液的浓度不变,当用于不同物质测定时,需要更改程序中的某些语句。程序通用性较差。为此,本文对谭新民导出多次加入法的函数式加以适当变换,得到一个新的函数式,然后,应用优选法中的0.618法直接求得样品溶液的浓度。作者选择几组测定数据上机运算,结果,算法的准确度与精度较为满意,运算时间短。对于不同的初始体积及各次标准加入
In recent years, there have been several different methods for the computer solution of ion-selective electrode multiple standard addition methods. Fu Min Gong, who proposed a number of consecutive standard addition method of calculation procedures, although the program has the advantages of simple structure, faster convergence, but it requires the sample solution volume and standard solution volume added to 100: 1, each adding standard solution The concentration of the same, when used in the determination of different substances, you need to change some of the procedures in the statement. Program versatility is poor. To this end, this article Tan Xinmin multiple derivation derived from the formula to be properly transformed to get a new formula, and then, the application of the optimal method 0.618 method directly determine the concentration of the sample solution. The authors choose several sets of measurement data on the computer operation, the results, the algorithm accuracy and accuracy are satisfied, the computing time is short. For different initial volume and standard addition
