摘要
介绍了用原子吸收法间接测定己二酸铵中的微量氯离子的方法,该法采用雾化增效剂增效、AgNO3与己二酸铵中的微量氯离子反应,测定剩余Ag+间接求出氯离子的含量,测定的相对标准偏差1.9%～4.8%,灵敏度(1%A)为0.022mg/L。
The method for the indirect determination of trace chlorine in ammoniun adipate by atomic absorption spectrometry is introduced,using atomization synergist, AgNO3 reacts with the trace chlorine in ammoniun adipate, the surplus of Ag+ in the solution is determined for calculating chlorine content. RSD of the method is 1.9%～4.8%,the sensitivity (1%A) is 0.022 mg/L.
