采用微波法消解催化剂 ,研究确定了微波消解催化剂的最佳工作条件。应用零交截距导数分光光度法解决了 PAR- CO2 +、PAR- Ni2 +体系中 Co2 +、Ni2 +的同时测定。钴和镍的线性范围分别为 0～ 30 μg/ 2 5m L和 0～ 2 5μg/ 2 5m L,催化剂样品中钴和镍测定结果的相对标准偏差 (n=5)分别≤ 1 .5%和≤ 1 .0 % ,与标准值相对误差分别≤± 1 .5%和≤± 2 .1 %。本方法测定催化剂中钴和镍 ,酸用量少 ,降低了环境污染 Microwave digestion of the catalyst to study to determine the microwave digestion catalyst for the best working conditions. Zero Cross Intercept Derivative Spectrophotometry was used to solve the simultaneous determination of Co2 + and Ni2 + in PAR-CO2 + and PAR-Ni2 + systems. The linear ranges of cobalt and nickel were 0-30 μg / 25 m L and 0-2 5 μg / 25 m L, respectively. The relative standard deviations (n ​​= 5) of the results of cobalt and nickel in the catalyst samples were ≤ 1.5% and ≤ 1.0%, relative standard deviation ≤ ± 1.5% and ≤ ± 2.1% respectively. The method determines the amount of cobalt and nickel in the catalyst, reduces the amount of acid used, and reduces the environmental pollution
