How to detect the gold concentration using UV in a hydrochloric acid system
Thread Content
Currently, solutions with different concentrations are prepared using chloroauric acid for extraction; after the extraction, UV detection is intended to be used to measure the concentration in the raffinate. Has anyone ever used UV detection to measure the gold concentration in solutions? Thank you
You should first determine, based on chemical principles, whether the complex or association between chloride ions and gold ions exhibits significant ultraviolet absorption, and then decide whether ultraviolet absorption spectroscopy can be used for determining the concentration. Such information can be found in specialized sources, such as analytical chemistry manuals and the ultraviolet spectra of compounds characteristic of gold ions. Or directly conduct the condition test for the UV spectrum using the solution from your experiment.
