- Determination of silver concentration in tomato seeds (Solanum Lycopersicum L.) exposed to silver nanoparticles using AAS-F and a validated method Luis Octavio Hernández Arteaga Marcos Loredo Tovias René Araujo Martínez Martha Eugenia Compeán Jasso Idania de Alba Montero Facundo Ruiz Multidisciplinarias (Ciencias Sociales) uptake Tomato seeds silver nanoparticles The interaction of silver nanoparticles with Tomato seeds (Solanum Lycopersicum L.) was studied; the amount of silver uptake by tomato seeds was quantified by using flame atomic absorption. The absorption analysis was carried out according to the performance study of the method to estimate the detection and quantification limits as well as the accuracy. The seeds were exposed at different silver concentrations and different times. A simple method has been developed for the determination of silver content in aqueous matrices by acid digestion followed by atomic absorption spectroscopy flame; it was found that the acid digestion is efficient for extraction of the analyte in a single step. The limits of quantification achieved in the analytical method allow the determination of silver on plant tissue, the highest silver uptake in the tomato seeds was obtained with the treatment using the highest silver concentration (10 mM) and longer exposition time (48 h). 2018 artículo científico 0188-6266 https://www.redalyc.org/articulo.oa?id=41658091008 https://www.redalyc.org/journal/416/41658091008/ https://www.redalyc.org/journal/416/41658091008/html/ https://www.redalyc.org/journal/416/41658091008/41658091008.epub https://www.redalyc.org/journal/416/41658091008/movil https://doi.org/10.15174/au.2018.2024 en http://www.redalyc.org/revista.oa?id=416 Acta Universitaria application/pdf Universidad de Guanajuato Acta Universitaria (México) Num.5 Vol.28
