摘要
阐述了硝酸-高氯酸消解、火焰原子吸收法直接测定工业废水中总铬。方法特征灵敏度0054mg/L(1%吸收),检测限0036mg/L,加标回收率96%～102%,相对标准差1%～17%。
Chromium in waster water was determined by flame AAS with HNO 3 HClO 4 digestion. The sensitivity of the method was 0 054 mg/L(1%absorption) . Detection limit was 0 036 mg/L. Recovery was in the range of 96%～102 %. RSD was 1%～17%.
