Quantitative detection of Cu element in Yellow River water based on LIBS-GD combined technology
In response to the shortcomings of the current methods for detecting heavy metal elements in liquid,the laser-induced breakdown spectroscopy-glow discharge(LIBS-GD)combined method is introduced for detecting Cu element in the Yellow River water.By measuring the Cu mass concentration of different standard solutions,a standard curve for Cu is established using the internal standard method,resulting in a detection limit of Cu element of 0.045 mg/L.The Cu mass concentration of the Yellow River water at different sampling points is measured experimentally using LIBS-GD,and the measurement results are compared with those of flame atomic absorption spectroscopy(AAS)method.The results show that the two methods have good consistency.The LIBS-GD combined technique demonstrates good performance in detecting Cu element,offering a more convenient and efficient option for heavy metal elements detection in water body.
