Abstract
Process analysis and optimisation requires accurate sensing and measurement of the key parameters. In mineral leaching process, particularly for copper and uranium, measuring and controlling ferric ion (Fe3+) concentration is crucial for optimal mineral recovery rates. Chemical sensors that emit light – luminescence - are known for their ease of use, quick reaction time, and exceptional ability to detect various substances with great accuracy and sensitivity. In this research project, a novel chemical sensor device was developed for Fe3+ ion measurements in mineral leaching conditions using lanthanide metal organic framework with excellent optical properties and selectivity towards the ferric ion. The framework was incorporated in a hydrogel matrix, which was then used to coat an optical fiber, and produced a fast, practical Fe3+ sensor prototype.
