对程序控制温度湿法消解湿地越桔样品中铅的消解条件和石墨炉原子吸收光谱仪的测定方法进行了研究和探讨。在本法选择的条件下,回收率为95.8%～104.2%,相对标准偏差为4.78%。经t检验与国家标准方法的对比实验证明,二者无显著差异。
The conditions for the digestion of lead in wet-digested samples by wet-process digestion and the determination of lead by graphite furnace atomic absorption spectrometry were studied and discussed. Under the conditions selected by this Law, the recoveries ranged from 95.8% to 104.2% with a relative standard deviation of 4.78%. The t test and the national standard method of comparative experiments show that there was no significant difference between the two.
