| 摘 要： | 用电感耦合等离子发射光谱法测定了Al2O3基催化剂中的Pt,考察了基体及所用试剂对Pt测定的影响,发现Al2O3基体、硫酸等对Pt测定均有负干扰,应在标准溶液与基体匹配的情况下进行测定。该方法的检出限为Pt0.10mg/L;样品的加标回收率96%以上。

| Abstract: | The content of Pt in catalysts supported on aluminum oxide is determined by ICP-AES. The influence of carriers and reagents on the determination is inspected and the results show that the Al 2O 3 carrier and H 2SO 4 have interference on the results, so the matrix matching method should be applied in the determination. The limit of Pt of the determination is 0.10mg/L, and the recovery is higher than 96%. |
