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、成本低的特点
In order to establish a chemical method capable of simultaneous determination of iron and copper in industrial wastewater, a stable coordination compound of iron, copper with 5 Br PADAP and Triton X 1 0 0 in pH2 .67 buffer was proposed. In a certain wavelength range, Spectrophotometer for multi-wavelength measurement, the measured data input computer, using the method of multiple linear regression method with high sensitivity and good selectivity, the recovery experiment results are satisfactory, the recovery rate of 96.0% ~ 10 3.3% between the use of this method can better eliminate the interference of industrial wastewater coexisting components, the determination of iron, copper content, but also has the characteristics of simple, fast, low cost
