Rare earth elements (REEs) are essential to most renewable energy technologies. Unfortunately, as we transition sustainable production, the demand for REEs rapidly grows well beyond current rates of production. As a result, novel means efficient, scalable, and easily adaptable methods processing primary recycled feedstocks needed. Development integration sensors highly selective in-line monitoring can support more efficient design testing such separation processes cost-effective deployment those flowsheets. Work here will explore application fluorescence spectroscopy, sensitive technique, quantify multiple lanthanides in complex mixtures, including known interferents or quenching agents. Results include identification optimal excitation wavelength limit detection various rare elements, performance data-science-based quantification approaches streams where "unknowns" present. Overall, data science tools conjunction with optical sensor were able analytes presence other anticipated be actual industrial stream. Here, characterization microfluidic device similar used new process development. This study demonstrates capability utilizing spectroscopy complicated solution matrix, suggesting this successful approach optimize efficiency an
