Conteúdo: |
An analytical method was developed for determination of Cd, Sn, Pd, Pt and Rh in sediments, fertilizer and sludge samples by inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). The performance of ICP-MS/MS using oxygen into the octopole reaction system (ORS3) and MS/MS mode, on mass and shift mass, was evaluated to overcome spectral interferences. Addition and recovery experiments in sediments, fertilizer and sludge samples at three concentration levels, 0.5, 1.0 and 5.0 μg L− 1, were carried out to evaluate the accuracy of the developed procedure. Quantitative recoveries, from 80 to 113% for 112Cd+, 120Sn+ and 106Pd+ were reached using MS/MS in on mass operation mode. For Pt and Rh, recoveries ranged from 81 to 117% by monitoring 195Pt16O+ and 103Rh16O+ in MS/MS (shift mass mode) with 0.3 mL min− 1 oxygen gas flow rate pressurized into the ORS3. Limits of detection of the developed method were 15, 2.5, 1.8, 9.0 and 9.9 μg kg− 1 for 195Pt16O+, 103Rh16O+, 112Cd+, 120Sn+, and 106Pd+, respectively. All analytes were simultaneously interference-free determined by ICP-MS/MS, which demonstrates the potential of this instrumental analytical strategy for Cd, Sn, Pd, Pt, and Rh determination in complex samples. |
