| 摘 要： | 研究了用流动注射分析进行阻尼最小二乘分光光度法同时测定锌、铜和钴的新方法。方法基于阻尼最小二乘法改进CPA法，将阻尼因子和非零截距引入CPA法，降低了P系数矩阵的病态程度和改善了校正模型的预报能力，使结果更加准确，已将方法成功用于锌铜钴混合体系的分析。

| Abstract: | The paper reported that FIA and a modified CPA method for multi-component analysis was applied to simultaneous determination of zinc, copper and cobalt. The method was based on the principle of damper least squares. A damper factor and nonzero intercept were introduced into the P coefficient matrix, which could reduce the abnormality of the P coefficient matrix and make the results more accurate. The method was successfully applied to the simultaneous determination of zinc, copper and cobalt. |
