银属于贵金属,极易与汞生成汞齐.在大多数支持电解质中,银的还原电位是在汞的溶出波之前.如有适当络合剂存在的支持电解质中,银的还原波能与汞的溶出波分开.但此时有其他元素的干扰,甚至 Silver is a noble metal that easily forms mercury with mercury. In most supporting electrolytes, the reduction potential of silver is prior to the elution wave of mercury, and in the supporting electrolyte with the appropriate complexing agent, The dissolution of the wave separated, but this time there are other elements of interference, even
