This report proposes a refined method to date archaeological gold samples based on the Tafel analysis of the ascending part of voltammetric curves corresponding to the oxidation of surface flakes of gold in contact with hydrochloric acid aqueous electrolyte. This allows estimating the equilibrium potential of gold oxidation correcting for irreversibility effects. This equilibrium potential can be correlated with the coverage of adsorbed oxygen species and hence the estimated age of the gold samples. A satisfactory potential/time calibration graph was constructed from a set of archaeological samples including two sets of samples from the Mapungubwe Gold Collection, South Africa (1200–1290 CE) and Santa Llúcia, Alcalà de Xivert in Spain (dated back 600-550 BCE) sites. The dated samples come not only from different continents, but their ages also cover more than 3000 years.

本报告基于伏安曲线的上升部分的塔菲尔分析（对应于与盐酸水溶液接触的金表面薄片的氧化），提出了一种精确的日期考古金样品的方法。这允许估计金氧化的平衡电位，以校正不可逆效应。该平衡电位可以与吸附的氧物种的覆盖率相关，因此可以与金样品的估计年龄相关。从一组考古样本中构建了令人满意的电势/时间校准图，其中包括南非Mapungubwe黄金收藏馆（公元1200-1290年）和西班牙阿尔卡拉特希弗特的SantaLlúcia（可追溯到公元前600-550年）的两组样本）网站。注明日期的样品不仅来自不同的大陆，
