摘要
用王水和高氯酸溶样,以高氯酸和盐酸为测定介质,并控制合适的酸度,最后用原 子吸收光谱法测定铜精矿中的银.该法简单、分析快速,易于掌握.该法检出限为O.0026 mg/L,回收率为97.3％～102.5％,变异系数小于3.82％.
The sample is dissolved in aqua regia and perchloric acid. Perchloric acid and hydrochloric acid are selected as a determination medium, and their acidity is controlled reasonably . Then Ag in the copper concentrate is determinated by the atomic absorption spec-trophotometry. The method is simple and rapid, and it is easily grasped. The test results show that the detection limit is 0. 0026 mg/L, the recovery is 97.3%~102.5% and the vari-able coefficient is less than 3. 82%.
