摘　　要：在简单的酸性介质中微分电位溶出法测定锡,灵敏性很低,且受铅的严重干扰,该文研究在草酸-甲苯胺蓝介质中,微分电位溶出法测定罐头食品中锡,灵敏度高,不受铅的干扰,结果回收率为93.5%～107.6%,最低检出限为5.0μg/l。if one determines tin with different ial electric potential method of dis solution in acid medium,the sensiti vity is low and it will be seriously affected by lead.This paper is a study of measuring tin in the media of oxalic acid and tolui-dine blue.The sensitivity is high an d it is free of the interference of lea d.The recycling rate is 93.5%～107.6%.The minimum amount determined is 5.0ug /l.
