| 摘 要： | 原子吸收分光光度法测定银是一个较简便、快速的方法。但由于灵敏度的限制,不得不采取一些有效措施如分离富集等手段来满足生产上的要求。本文探讨了N_(26(?))国产季胺型液体交换树脂萃取色层分离、富集银的行为。经实践证明,在有一定量氯离子存在下,N_(263)能定量吸附银,1∶1盐酸淋

| Abstract: | The behaviour of enriching silver by extraction chromatography with N263
liquid resin w"as studied. The optimum conditions of the adsorption and elu-
tion of silver were examined: The elimination and interference of foreign ions
were tested. This method could detect more than O.Ox ppm of silver in ores
(sample taken :5g0. |
