- Abstract
A novel method for the determination of palladium in tetrakis (triphenylphosphine) palladium catalyst samples was established by inductively coupled plasma atomic emission spectrometry after samples digested by teflon pressure digestion vessel with aqua regia. Such experiment conditions were investigated as the influence of sample digestion methods, digestion time, digestion temperature and interfering ions on the determination. Under the optimized conditions, the linear range of calibration graph for Pd was 0 ~ 250.00 mg L-1, and the recovery was 98.40% ~ 103.60%. The relative standard deviation (RSDs) for Pd was 1.78 %. The proposed method was applied to determine the same samples with atomic absorption spectrometry with the results consistently, which is suitable for the determination of palladium in tetrakis (triphenylphosphine) palladium catalyst samples.
