摘　　要：本文提出了用苏本精—钒(Ⅳ)—草酸催化导数极谱测定天然水中痕量锗的方法。对底液的组成和天然水中常见的共存离子的影响进行了实验。方法简便,灵敏度高,选择性好,不用分离富集,直接用于测定天然水中痕量锗。In this paper,it is suggested that the procedure carried out by catalytic derivative polarograph in Haematin-v( Ⅳ )-oxalic acid system is employed as determing trace Germanium in natural water. The constituents of background electrolyte and the onfluence of ions which exist in natural water are experimented,The method is simple,with a high sensitivity,and of a good characteristic of selection and can be employed as determing trace Germanium in natural water without separation and concentration。
