【摘要】 提出了以ICP -AES测定催化剂中钯含量的方法。考查了试样的分解方法 ,载体及所用试剂对钯测定的影响 ,发现氧化铝载体、硫酸等对钯的测定均有负干扰 ,2 %王水、2 %高氯酸对钯的测定无影响。提出采用载体匹配法测定Pd/Al2 O3 中钯的质量分数 ,该方法简单、准确、快速 ,回收率在 95 %以上。更多还原

【Abstract】 A method for determining palladium content in catalysts supported on active carbon and aluminum oxide by ICP-AES was reported.The dissolution conditions of catalyst samples as well as interference conditions of inorganic acid and carrier were inspected.The recoveries are more than 96%,and the relative standard deviation of palladium determination on six samples are lower than 3%.更多还原
