Abstract: This paper proposes a novel method for detecting trace uranium in water, based on the synergistic coupling of the copper electrode surface microstructure with electrochemical enrichment. Microstructures were fabricated on the copper electrode surface using a nanosecond laser (10 ns, 1064 nm), after which the surface oxide layer was removed using dilute hydrochloric acid. Trace uranium in water was enriched using electrochemical enrichment technology and subsequently analyzed using laser-induced breakdown spectroscopy. The U II 409.013 nm characteristic emission line was selected as the analytical target. We systematically investigated the influence of the microstructure fabrication parameters, electrochemical enrichment parameters, and laser excitation parameters on the enhancement of the U II 409.013 nm line signal, with particular emphasis on analyzing the relationship between the microstructure morphology and spectral line intensity. The experimental results demonstrated that the microstructures on the electrode surface enhanced the characteristic uranium emission line intensity by nearly one order of magnitude, achieving a detection limit of 20.0 μ g l−1 (relative standard deviation, RSD = 4%). By characterizing the microstructure morphology and calculating plasma parameters, the enhancement mechanism of the uranium characteristic spectral line was identified as a threefold effect: (1) the microstructures significantly increased the effective surface area of the electrode; (2) the field enhancement effect of the microstructures effectively reduced the plasma excitation threshold and improved the ionization efficiency; (3) the microstructures enhanced the electrochemical enrichment effect by improving the hydrophilicity of the electrode surface. This method provides an innovative analytical approach for monitoring heavy metal pollution in water bodies and for detecting radioactive elements in marine environments. [ABSTRACT FROM AUTHOR]
