摘要
采用微波消解的方法,考察了HF用量对车用陶瓷催化转化器中贵金属元素测定结果的影响。结果表明:样品为0.5 g,HF用量为1 m L时,测定结果最大,该方法回收率高,再现性好,精密度令人满意。
The influence of HF addition on analytical results of noble metal elements in car-use ceramic catalytic converters was investigated. The maximum value of determination of noble metal elements reached when 1 mL HF was added into 0.5 g of samples. The results show that the method has high recoveries, good reproducibility and satisfactory precisions.
