| 摘 要： | 根据钯（Ⅱ）与１－（５－溴－２－吡啶偶氮）－２－萘酚－６－磺酸（５－Ｂｒ－ＰＡＮ－Ｓ）形成稳定络合物这一物质，利用阴离子交换树脂为吸附载体，建立了离子交换树脂相光度法测定钯的新方法。以最大吸收波长６９０ｎｍ为测定波长，８００ｎｍ为参比波长，用双波长法进行测定，灵敏度高，选择性，重现性好，钯量在０￣２０μｇ范围内服从比尔定律。方法用于合成水样及催化剂中钯的测定，结果满意。

| Abstract: | A new method for the determination of palladium by ion exchange resin phase spectrophotometry has been established. It is based on the fixation of palladium as 1-(5-bromo-2-phridylazo)-2-naphthol-6-sulphonic acid (5-Br-PAN-S) compelled on a anion-exchange resin. The resin phase absorbances at 690 and 800 nm are measured directly and the linear range of 0-20 micrograms for palladium. The method has been applied to the determination of palladium in water samples and catalysts with satisfactory results. |
