| 摘 要： | 多波长Ｋ系数方程法同时测定水样中Ｃｕ２＋、Ｃｏ２＋、Ｃｄ２＋，即选定三个测定波长，分别将三组分在两个波长处的吸光度转换为另一波长处的吸光度，即可列出一个多元一次方程组，进而解出此波长处各组分的吸光度，求得各组分的含量。对水样中的Ｃｕ２＋、Ｃｏ２＋、Ｃｄ２＋三组分同时测定，结果令人满意。

| Abstract: | In this paper,a multi wavelenth K factor equation method for simultaneous determination of Copper Cobalt Cadmium in wastewater is presented.That is,selecting three wavelength,changing the absorbance of the three components at two warelenth to the absorbance of another wavelength respectively.Then a equation set is constructed.By using the equation set,the contents of components can be obtained.The method has been applied to determining Copper Cobalt Cadmium in waste water with satisfactory results. |
