摘要
在Gordon模型的基础上,我们用导数峰值法和多点标准加入法来测定酸碱组分的pK值及其含量。在T′～pH导数峰图形上,峰位对应于组分的pK值,峰高正比于组分的浓度,我们测定了几种单元酸、多元酸及混合酸,并设计了“PEAK”程序和“SEACH”程序进行计算、绘图和优化。
On the basis of Model gordon, the 'derivative peak value method' and 'many points standard addition method' were used to determine the pK of acid or base and its concentration.
In the T'-pH figure of this paper, the position of the peak corresponds to the pK value of the component, the peak height is directly proportional to its concentration. Several monobasic weak acids polybasic weak acids and mixture of acids have been determined with the programmes PEAK and SEACH designed to calculate、draw and optimize.
