【摘要】 研究了氢化物发生-原子荧光光度法测定水中微量砷和硒的条件及方法.结果表明,检出限砷为0.031 5μg/L,硒为0.032 6μg/L,11次测定的相对标准偏差为0.37%~0.61%;标准回收率砷为97.5%~101.2%;硒为95.9%~102.8%.方法简便、快速、灵敏,适于生活饮用水、地表水和水源水中微量砷、硒的同时测定.更多还原

【Abstract】 A convenient and rapid method for trace of As and Se were determined by hydride generation atomic fluorescence spectrometry(AFS) in running water.The results show that:(1) the detection limits of this method were 0.031 3μg/L(As) and 0.038 2μg/L(Se) respectively;(2) the relative standard deviation was 0.37%～0.61%(n=11),and the recovery was 97.5%～101.2%(As) and 95.7%～102.6%(Se) respectively.The method can be a useful tool on determining As and Se in running water,land-surface water and source water.更多还原
