原子吸收光谱法对铜精矿中微量银的测定

Determination of Trace Silver in Copper Concentrate by Atomic Absorption Spectrometry

根据云锡铜业分公司铜精矿中微量银的原子吸收光谱法测定的生产实践,研究铜精矿酸溶解 后共存在以王水为介质的各种共存元素对银的火焰法测定是否产生干扰,验证了原子吸收光谱法对铜精 矿中微量银测定的实用性.

According to the production practice of Yunnan Tin Group Copper Branch office on deter^nination of trace silver in copper concentrate by atomic absorption spectrometry,the paper makes a research on whether there is interfere of the various coexisted elements （taking aqua regia as medium） existed in copper concentrate after dissolution on the deter^mination of silver flame method, and the pap er proves the practicability of determination of trace silver in copper concentrate by atomic absorption spectrometry.
