采用“低温熔化－中温挥发－硝酸高氯酸消化溶解”的方式进行样品处理，用电感耦合等离子体发射光谱（ICP－AES）法同时测定了醋酸塔流动液中的钼和镍。该方法操作简便、快速，干扰少，测定精密度为0．6％～0．8％，方法回收率在99％～102％之间。
The samples were treated by “low temperature melting - medium temperature volatilization - nitric acid perchloric acid digestion and dissolution”, and the molybdenum and nickel in the acetic acid tower liquid were simultaneously determined by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). The method is simple, rapid, less interference, determination of precision of 0.6% to 0.8%, the method recovery was between 99% to 102%.
