Abstract
En este trabajo, la presencia de las fases cristalinas, el tamaño de las partículas (PM) y la caracterización química de los sedimentos depositados en los techos construidos con chapa acanalada de viviendas cerca de la planta de cemento en el distrito de Caracoto, San Román, Puno, Perú, fueron determinados. Las fases cristalinas estudiadas por difracción de rayos X (DRX) y espectroscopía de Raman fueron: calcita, cuarzo, antigorita y anatasa, presente en las muestras de sedimento, relacionado con los procesos químicos dentro de los hornos. Los elementos químicos con mayor concentración atribuidos a la industria del cemento, tales como Ca> Si> Al> Fe, y trazas de elementos tales como Zr> Ba> Mn> Cr> Pb se analizaron por fluorescencia de rayos X. Los sedimentos en ambos lados (uno que estaba pegado a la cara interna de la lámina corrugada y la otra que estaba expuestas al aire) se estudiaron mediante microscopía electrónica de barrido (SEM), con diferencias en el nivel topológico y químico. También se estudiaron las fotomicrografías obtenidas por MEB permitiendo así el cálculo del tamaño y el porcentaje de material particulada.
In this paper, the presence of the crystalline phases, the size of particulate matter (PM) and chemical characterization of sediments deposited on the roofs constructed with sheet metal grooved of homes near the cement plant in the district of Caracoto, San Roman, Puno, Peru, were determined. The crystalline phases studied by X-ray diffraction (XRD) and Raman spectroscopy were: calcite, quartz, antigorite and anatase, present in the sediment samples, related to the chemical processes inside the furnaces. Chemical elements with higher concentration attributed to the cement industry, such as Ca> Si> Al> Fe, and traces of elements such as Zr> Ba> Mn> Cr> Pb were analyzed by X-ray fluorescence. Sediments in both sides (one that was stuck to the internal face of the foil corrugated and the other that was exposed to the air) were studied by Scanning Electron Microscopy (SEM), with differences in topological and chemical level. Also the photomicrographs obtained by MEB were studied allowing thus the calculation of the size and percentage of particulate matter.
