介绍了使用亚硝基红盐法实现准确测定回收醋酸钴、醋酸锰混合催化剂中钴含量约为13％的产品，讨论了酸度、干扰物、反应时间对测定的影响。结果表明，该法精密度高，准确度好。 This paper introduced the accurate determination of the recovery of cobalt acetate by using nitroso red salt method. The cobalt content in the mixed catalyst was about 13%. The effects of acidity, interferences and reaction time on the determination were discussed. The results show that the method has high precision and good accuracy.
