Abstract

A rapid spectrophotometric method for the determination of 0.1-1.0% of palladium in titanium alloys with dimethylglyoxime is described. The complex is extracted with chloroform and its absorbance measured at 380 nm. Beer's law is obeyed and the molar absorptivity is 170 l.mol(-1).mm(-1). None of the elements in common titanium alloys interfere. The method is rapid, simple and reproducible.

摘要

本文描述了一种用丁二酮肟快速分光光度法测定钛合金中0.1 - 1.0%钯的方法。该络合物用氯仿萃取，在380nm处测量其吸光度。符合比尔定律，摩尔吸光系数为170 l·mol⁻¹·mm⁻¹。常见钛合金中的元素均不产生干扰。该方法快速、简单且可重复。
