摘要
通过对不同银量产生的氯化银沉淀对钯的吸附试验,以及盐酸沉淀分离基体后溶液中的Ag、Cu、Fe、Pb、Bi、Sb、Te的干扰试验,建立了盐酸沉淀分离银电解液中的基体银,火焰原子吸收光谱法测定银电解液中Pd的分析方法。在5%的混合酸介质中测定Pd时,灵敏度高,线性范围0.3~3 ug/m L,相关系数0.9999.该方法应用于实际样品的分析,相对标准偏差为0.94%,加标回收率介于97%~102%之间。
Through different amount of silver chloride precipitation of palladium adsorption test, and hydrochloric acid precipitation separation matrix solution of silver, copper, iron, lead, bismuth, antimony and tellurium interference test, hydrochloric acid precipitation separation matrix of silver in silver electrolyte and flame atomic absorption spectrometry determination method for the determination of palladium in the silver electrolyte is established. When determining in 5% of the mixed acid medium for the determination of palladium, sensitivity is high, linear range is of 0.3 ~ 3ug/m L, the correlation coefficient is of 0.9999. When the method is applied to the analysis of real samples, the relative standard deviation is 0.94% and recoveries ranged is between 97% ~ 102%.
