针对电气行业废水中含氟物质的新型检测传感器的构建与应用
Design and application of a novel detection sensor for fluorine-containing substances in electrical industry wastewater
摘要
Abstract
The rapid monitoring of fluorine-containing substances in wastewater from the electrical industry serves as a critical approach for effectively managing environmental risks posed by emerging contaminants like perfluorooctanoic acid(PFOA),holding significant implications for building a clean and beautiful world.This study develops a novel detection sensor based on gold nanoparticle-doped molecularly imprinted polymers(Au@MIP).By optimizing the o-phenylenediamine(o-PD)-chloroauric acid electropolymerization process(no-PD∶nPFOA=10∶1,30 cyclic scans),highly selective PFOA detection is achieved with recovery rates of 109%～114%.Integrated with an early-warning module,the system enables quantitative PFOA analysis within 45 min across a range of 0.04～100 ng·L⁻¹,accomplishing both trace-level environmental monitoring and precise quantification in high-concentration contamination areas.The results demonstrate the superior performance of the Au@MIP electrode-based sensor,providing technical support for in-situ monitoring of industrial wastewater.关键词
