[Determination of lead and arsenic in copper aspirinate by graphite furnace atomic absorption spectrometry].
A graphite furnace atomic absorption spectrometric method has been established to determine trace lead and arsenic in copper aspirinate, a new anti-inflammatory and anti-thrombotic agent. The sample is pretreated by ashing at 530 degrees C in the presence of Ni (NO3)2, followed by dissolution with HNO3. The method is simple and has a low detection limit. The relative standard deviation is 11%-15%, the recovery is 92%-112% for lead and 86%-119% for arsenic.
