一、概况Zuberbuhler 等人应用改进的 Gauss-Newton 法即 Marquardt-Gauss Newton 法编写了应用于多波长光度法测定二元及多元配合稳定常数的 SPECFIT 程序,并对其数学模型作了讨论,但在一般微机上不能运行。我们参照了 SPECFIT 程序,用FORTRAN-77语言编写了 SPU 与 SPF 二个程序。当配合物体系中摩尔吸光值ε全部未知时,应用 SPU 程序;ε部分未知时,应用 SPF 程序,且均可在微机上运行。我们应用多波长光度法测定的配合物稳定常数与我们用 PH-电位法测定的结果以及其它文献值进
First, the general Zuberbuhler et al. Application of improved Gauss-Newton method that Marquardt-Gauss Newton method for the preparation of multi-wavelength spectrophotometric determination of binary and multiple matching stability constant SPECFIT program, and its mathematical model was discussed, but in the General computer can not run. We refer to the SPECFIT program, written in the FORTRAN-77 SPU and SPF two programs. When all the molar absorptivity ε in the complex system is unknown, the SPU program is applied. When the ε part is unknown, the SPF program is applied and can run on the microcomputer. We applied the multi-wavelength photometric method to determine the stability constants of complexes with the results of our measurements by PH-potentiometry as well as other literature values
