| 摘 要： | 利用任一ｐＨ下被测组分的分布系数，提出ｐＨ校正最小二乘法。对不同ｐＨ的试样进行分析，既可简化分析步骤又可提高准确度。该ｐＨ校正原理同样适合于其它化学计量学光度法。利用该法对焦化废水中的吡啶、苯酚、萘混合三组分进行同时测定，得到了满意的结果。

| Abstract: | The pH-corrected Least Squares(pH-CLS)method was developed by use of the distribution coefficent of seriese at any pH. By this method the analytical prosseses could be simplified and the accuracy could be increased.The pH-CLS principle is suitable to the other chemomstric'sspectrophotometry as well.The method was satisfactorily applied to the spectrophtometric resolution of pyridine,phenol and naphthalene in a waste water of a coke chemical factory. |
