摘要
系统研究了氢还原重量法测定氯化钯产品中钯含量的测定条件,考察了杂质元素对钯分析结果的误差影响。结果表明:于选定条件下,测定59.78%-60.03%含量的钯,极差、标准偏差(SD)、相对标准偏差(RSD,n=22)和重复性限(r)分别为±0.01%,0.0047%-0.0050%,0.0079%-0.0083%和0.009%-0.014%,样品加标回收率达到99.98%,钯分析结果准确、可靠、精密度高。
A new analytical method for the determination of palladium in palladium chloride by hydrogen reduction gravimetric method were studied systematically.The effect of impurities on the content of palladium was investigated.The results indicated that the ranges,standard deviations(SD),relative standard deviations(RSD,n=22)and repeatability limits(r)were ± 0.01%,0.0047% -0.0050%,0.0079%-0.0083% and 0.009% -0.014%,respectively,with the palladium contents of 59.78% -60.03%in palladium chloride.The recovery of standard addition was 99.98%.The accuracy and precision of this proposed method are satisfactory.
