摘要
用硝酸、过氧化氢微波消解处理皮革样品,获得均匀的样品消解液。用原子荧光光谱法测定皮革中的砷和汞,并优化了测定条件。砷的相对标准偏差≤3.8%,方法检出限为0.0376μg/L,回收率为97.8%～102.8%;汞的相对标准偏差为≤7.2%,方法检出限为0.0046μg/L,回收率为95.0%～103.0%。
A uniform leather sample digestion solution was obtained firstly with the microwave digestion treatment method using nitric acid and hydrogen peroxide, and then the conditions for detecting Arsenic and Mercury in leather using atomic fluorescence method were optimized. The results indicated that the relative standard deviation was not greater than 3.8%, the detection limit was 0.0376 μg/L, the recovery rate was 97.8%-102.8% for Arsenic; and the relative standard deviation was not greater than 7.2%, the detection limit was 0.0046 μg/L, the recovery rate was 95.0%-103.0% for Mercury.
