自1979年瑞典D.丁agner首次提出电位溶出分析法(’)(Potent;ometr;e Str甚pping Analysis)以来,由于其仪器简单,操作简便,分析的精密度和灵敏度与明极溶出伏安法(ASv)、无火焰原子吸收分光光度法相似,尤对许多液体样品的分析具有显著的优点:不需消化样品、不用除氧,因而受到电? Since the first time in Sweden, D. Ding agner put forward the potential leaching method (Potent; ometr; e Str very pping Analysis), because of its simple instrument, easy to operate, the analysis of the precision and sensitivity and the Ming very stripping voltammetry (ASv), which is similar to flame atomic absorption spectrophotometry, has many significant advantages over the analysis of many liquid samples: it does not require digestion of samples, does not deoxygenate,
