摘要
用双硫腙显色分光光度法测定铁矿石中痕量铅,该方法具有简单、快速、灵敏等特点,用以测定铁矿石中的痕量铅,获得了满意的结果.检出限为0.06μg/mL,线性范围为0.00μg/mL～1.0μg/mL Pb^(2+),相关系数为0.9996,回收率89%～99%.
Trace lead in Iron ore was determined with double sulful-hydrozone color development spectrophotometric method. The method is simple, quick and sensitive .The result is satisfactory for the determining trace lead in Iron ore. The detection limit is 0.06μg/mL Pb^2＋ .The liner range is 0.00 μg/mL - 1.0 μg/mL Pb^2＋ . The related with coefficient is 0.9996 .The recovery rate is 89% - 99%.
