Resumen

El papel del litio en la transición energética exige mediciones de campo más rápidas y confiables en las cadenas de suministro basadas en salmueras. Presentamos una estrategia de LIBS orientada a proceso para la cuantificación en tiempo real de litio en salmueras en flujo. Un láser de 1064 nm, espectrómetros UV–Vis–NIR y una celda diseñada para minimizar la cavitación permiten generar plasma estable. Un flujo de datos guiado por la física (sustracción de línea base, extracción de rasgos, normalización interna y validación por nivel retenido) ofrece una calibración robusta en ~30–1300 ppm en matrices representativas. Las rutas de despliegue abarcan salares continentales, fluidos geotérmicos, aguas producidas en yacimientos de hidrocarburos y charcas hipersalinas marinas, lo que permite un mapeo denso, cribado ágil y el control de DLE en un lazo cerrado. La metodología acorta los ciclos de exploración, reduce la incertidumbre en la optimización de procesos y mejora la resolución espaciotemporal en la gestión del yacimiento. También se discuten las implicaciones de la gobernanza para un desarrollo responsable mediante el monitoreo químico in situ.
