摘　　要：为建立能同时测定工业废水中铁、铜含量的化学方法 本文提出铁、铜与 5 Br PADAP及TritonX 1 0 0在 pH2 .67缓冲液中生成稳定的配位化合物 ,在一定的波长范围内 ,用分光光度计进行多波长测量 ,测量的数据输入计算机 ,用多元线性回归法处理 本法具有较高的灵敏度和较好的选择性 ,回收实验结果也令人满意 ,回收率在 96.0 %～ 1 0 3.3%之间 采用本法能较好地消除工业废水中共存组分的干扰 ,对铁、铜含量进行选择性测定 ,而且具有计算简便、快速。The objective is to establish a chemical method for simultaneous determination of iron and copper in wastewater.The complexities of iron and copper with 5 Br PADAP and Triton X 100 can be obtained in pH2.67 ethanol medium. Within the limited wavelengths,the multi wavelength can be measured with a multi spectrophotometer.And the data thus obtained is input into computer and processed by using the multiple linear regression method.The sensitivity and selectivity with the above method are satisfactory.The percentage recovery is 96.0%～103.3%.The results are comparatively satisfactory.The chemical method can selectively determine iron and copper in wastewater when they coexist with interference. The method is simple,time saving and inexpensive.
