用原子吸收法测定了5批速效胃宁冲剂中Cd、Pb的含量。结果表明，该药物中含有一定量的Cd、Pb，但Pb含量高于Cd;批与批之间差别不大，说明工艺较稳定。
The contents of Cd and Pb in 5 batches of Weining Weining Granules were determined by atomic absorption spectrometry. The results showed that the drug contains a certain amount of Cd and Pb, but the content of Pb is higher than that of Cd. The difference between batch and batch is not big, which indicates that the process is stable.
