摘要
研究了用磷酸＋硫酸混合体系溶解氧化铝载体催化剂样品的条件和用火焰原子吸收法测定其银含量的方法。考察了测定过程中的干扰，经加标回收试验和重复性试验证明方法准确可靠。
method for the determination of silver in alumina supported catalysts by FAAS has been studiedSamples were thoroughly dissolved in H3PO4+H2SO4(2+1)Proper amounts of corresponding acids and Al were added to standard solutions and blank to match the prepared samples and to eliminate the interference effectsMeasurements of accuracy and precision of this method were obtained with a recovery test of added standards and a reproducibility test respectivelyThe satisfying results demonstrate that this method is applicable to the determination of silver in alumina supported catalysts
