快速测定海水和淡水中的痕量铀,是在悬汞电极上及在含铜铁灵、氨三乙酸、氯化钠的乙酸缓冲液中,于-0.25V搅拌富集2分钟,然后阴及扫描,铀(VI)呈现高灵敏的吸附溶出伏安峰,峰电位约为-0.48V(相对于饱和甘汞电极)。在0.3～7ppb铀峰高与浓度呈线性关系。作者认为铀(VI)-铜铁灵络合物正电极上的吸附是一种富集的方法。本法取样体积为 Rapid determination of trace amounts of uranium in sea water and freshwater is carried out by stirring at -0.25 V for 2 minutes on a hanging mercury electrode and in an acetic acid buffer solution containing tiantin, nitrilotriacetic acid and sodium chloride and then overcast Scanning, uranium (VI) exhibits a highly sensitive adsorption stripping voltammogram with a peak potential of -0.48V (vs. saturated calomel electrode). In 0.3 ~ 7ppb uranium peak height and concentration showed a linear relationship. The authors believe that the adsorption on the positive electrode of uranium (VI) -turnite complex is an enrichment method. The sample volume is
