The present study was conducted in Naranjo County located in the municipality of Mixco, Guatemala. The water supply source comes from two wells with a maximum flow of 25.24 and 33.44 L·s . The aim of this study was to conduct laboratory tests, basic engineering and supervision of the construction and evaluation of an operations plant using two configurations, A (low-rate sedimentation and ceramic filter) and B (high-rate sedimentation and clinoptilolite filter), to remove arsenic present in water for human use and consumption. This plant supplies water to Naranjo County in Mixco, Guatemala (5000 inhabitants). First, a laboratory Jar Test was performed to evaluate arsenic removal efficiency. And second, a conventional clarification plant was then built (design flow: 25.24 L·s ) for arsenic, values that comply with Guatemalan standards. For this case, the relation between Fe(III) dosage/mg and As(V) removal was 1:46.
Se desarrolló y validó una metodología para la cuantificación de ácido clofíbrico derivatizado con trimetilsilildiazometano en muestras de agua por cromatografía de gases acoplada a un detector selectivo de masas (CG-MS). El método se validó en diferentes parámetros como linealidad, exactitud, precisión,límites de detección y cuantifi cación. Las concentraciones de validación se encuentranen el intervalo de 0.0025 a 0.1644 ugL-1. Los límites de detección y cuantificación obtenidos son 0.0003 y 0.0053 ugL-1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
