针对某矿山坑探样品中钴量的测定,研究了利用原子吸收光谱法测定钴的样品前处理方法,确定出了高效的、危害性较小的、适用于矿山坑探样品钴量测定的样品处理方法,同时对本方法的精确度进行试验考查,其测定的RSD在1.3%～2.1%间,加标回收率在95.6%～103.4%间,充分表明了本方法具有较好的测定精密度和准确度,用于测定坑探样品中钴量可得到满意结果。
Aiming at the determination of cobalt content in a pit exploration sample, the sample pretreatment method for the determination of cobalt by atomic absorption spectrometry was studied, and the sample with high efficiency and less harmfulness suitable for the determination of cobalt content in a pit pit sample was determined Processing method, at the same time the accuracy of this method to test the test, the determination of RSD between 1.3% ~ 2.1%, the spike recovery of 95.6% ~ 103.4%, fully demonstrated that the method has good precision and Accuracy, for the determination of the amount of cobalt in pit exploration samples can be satisfactory results.
