The objective of this research is to assess heavy metal pollution and its fractionation in sediments the Sonora Bacanuchi rivers located arid semi-arid climates. Sediment quality guidelines (U.S. EPA; SQGs), enrichment factor (EF) geoaccumulation index (Igeo) were used evaluate extent pollution. Total metals concentrations for both as follows (mg/kg): Cd (< BDL), Cu (2 - 103), Cr (5 27), Fe (9156 34343), Mn (114 573), Ni (22 38), Pb (12 59), Zn (27 111). According sediment Cr, Ni, Pb,...
An experimental study on the acid hydrolysis of Cenchrus ciliaris particles was conducted. Input variables included particle size raw material (<0.053 mm and 0.16 mm), sulfuric concentration (0.05 0.15 M), reaction temperature (120–150 °C). Output concentrations xylose, glucose, arabinose, furfural in aqueous solution. Five chemical reactions involving decomposition monosaccharides were proposed, a pseudohomogeneous model consisting five ordinary differential equations developed. By means...
La calidad del agua para consumo humano es muy importante todas las naciones porque afectan significativamente al medio ambiente, en especial a la salud de los seres humanos provocando efectos tóxicos, además provocar enfermedades. El objetivo revisión hacer un análisis y comparar Normatividad Mexicana con Normas Extranjeras como son the United States Environmental Protection Agency [EPA], Bureau of Indian Standards [BIS], World Health Organization [WHO] así proponer recomendaciones, por lo...
<title>Abstract</title> The present study refers to the "El Lavadero" tailings deposit, considered a mining environmental liability (MEL), located near San Felipe de Jesús town, Sonora, in northwest Mexico; objective was determine total arsenic (As) content, its granulometric and geochemical distribution, mobilization capacity bioavailability. results oxidized unoxidized indicated low pH (potential of hydrogen) values (2.4–5.7) elevated concentrations (8235–36,004 mg kg<sup>− 1</sup>), which...
RESUMENSe validó el método para cuantificar aluminio (Al) en tejidos de ratas Sprague Dawley mediante espectroscopia absorción atómica por flama (EAA-F) y horno grafito (EAA-HG).La linealidad se evaluó coeficiente correlación (r), cuyos resultados fueron 1.000 0.9993 EAA-F EAA-HG, respectivamente.La exactitud fue 100.62 97.75 % recuperación, tanto que la precisión 0.61 1.30 del variación también condiciones repetibilidad; resultado obtenido indica es repetible las concentraciones utilizadas...
En esta investigación se caracterizó el potencial para la obtención de etanol a partir planta silvestre Cenchrus ciliaris, también conocida como zacate buffel. A estudios experimentales nivel laboratorio, determinaron los rendimientos técnicos y requerimientos energéticos las etapas pretratamiento ácido, hidrólisis enzimática fermentación. Los valores obtenidos fueron comparados con reportados en literatura otros procesos producción combustibles. resultados del presente trabajo indican que...
