| 摘 要： | 用5-Br-PADAP做显色剂,采用多波长线性回归-导数分光光度法同时测定镍、铜、钒。该法灵敏、准确。与CPA矩阵等方法相比,由于不需进行矩阵运算,只进行简单的数学处理,因而更方便。 |
| 关 键 词： | 线性回归 导数 分光光度法 镍 铜 |

| Abstract: | A method for simultaneous determination of nickel > copper and vanadium by multi-wavelangth linear regression derivative spectrophotometry is proposed. The result shows that accuracy and sensitivity of the method are satisfactory. Comparing with inverse least squares matrix mehtod, the method is simple and rapid, because simple mathematical calculation is only needed. |
| Keywords: | Multi-wavelength linear regression. Derivative spectrophotometry Nickel Copper Vanadium. |
