研究了Nafion修饰电极富集和阳极溶出伏安法测定废水中铅的方法。实验结果表明,方法检测限为0.03mg/L,线性测量范围为0.10～1.50mg/L。方法重复性相对标准偏差为6.1～18%,再现性相对标准偏差为10～22%。对实际样品测定的精密度以相对标准偏差表示为10～22%。回收率为70～97%。
A method for the determination of lead in wastewater by Nafion modified electrode enrichment and anodic stripping voltammetry was studied. The experimental results show that the detection limit of the method is 0.03mg / L and the linear measurement range is 0.10 ~ 1.50mg / L. The relative standard deviation of repeatability was 6.1-18% and the relative standard deviation of reproducibility was 10-22%. The precision of the actual samples was expressed as 10 to 22% with relative standard deviation. The recovery rate is 70 ~ 97%.
