Filtro de roca basáltica para agua residual

Abstract

Introducción. Se realiza un análisis fisicoquímico a la roca basáltica (escoria negra) de El Salvador paradeterminar la cantidad necesaria para la adsorción de químicos presentes en un litro de agua residualordinaria de Ciudad Real, en San Sebastián Salitrillo, en el departamento de Santa Ana.Objetivo. Determinar el modelo cinético de adsorción (isoterma de Langmuir, Freundlich, Temkin y Henry que mejor se ajuste al equilibrio de adsorción entre el azul de metileno y la roca basáltica. Se mide la constante del equilibrio de adsorción-desorción formado entre el azul de metileno y la roca basáltica para determinar el área específica de la roca basáltica y establecer el número de sitios activos de absorción por nanómetro cuadrado de roca basáltica. Metodología. La técnica utilizada para el tratamiento del azul de metileno fue la adsorción, ya que es económico y competitivo frente a otros métodos convencionales. Se estudió el efecto de adsorción con 5, 10, 15, 20, 25, 30, 33 ppm de azul de metileno en presencia de 1 gramo de roca basáltica pulverizada durante 30 minutos, tomando alícuotas cada 5 minutos; la adsorción se midió con un espectrofotómetro UV-VIS Cary50.Resultados. Se evidencia una buena adsorción debido a que después de 20 minutos llegó a ser constante y tiene una buena superficie específica. El isoterma que mejor se le aplica es Langmuir, debidoque su coeficiente de correlación es el más cercano a uno.
