【摘要】 采用大孔型强碱性阴离子交换树脂在稀硫酸中吸附分离痕量铀,盐酸—硫酸混合液淋洗杂质,提高了分析结果的准确度、重现性好、操作容易。应用于标样分析,误差<±15％,还可定置测定同一称样中的微量铅。更多还原

【Abstract】 A strong basic macroporous anion exchanger was used to separate trace uranium from a dilute sulfuric acid medium. The adsorbed impurities were leached with HC1-H2SO4. The operations were easy, with satisfactory repeatability. The method has been applied to the analysis of some reference samples and can be adapted for "use with quantification of μg levels of lead in the same sample.更多还原
