In the process of electrochemical deposition of metals, the additives can directly affect the final morphology of the metal. Using glyphosate as the additive, copper thin films were prepared by the electrochemical deposition method from a CuSO aqueous solution under a specific voltage. The copper thin films were grown on the surface of the indium tin oxide (ITO) film, which was used as the working electrode in a classical three-electrode cell. Glyphosate combined with the copper ion to form a complex, and hindered further reduction and crystallization of the copper ions. The results indicated that the peak intensities of the X-ray diffraction peaks decreased with the increase in the glyphosate concentrations, which can be used as a basis for quantitative detection. The method is simple and highly sensitive.
在金属的电化学沉积过程中，添加剂会直接影响金属的最终形态。以草甘膦作为添加剂，在特定电压下通过电化学沉积法从硫酸铜水溶液中制备铜薄膜。铜薄膜生长在氧化铟锡（ITO）薄膜表面，该薄膜在经典三电极电池中用作工作电极。草甘膦与铜离子结合形成络合物，阻碍了铜离子的进一步还原和结晶。结果表明，X射线衍射峰的峰强度随草甘膦浓度的增加而降低，这可作为定量检测的依据。该方法简单且灵敏度高。
