Remocion de Metales Pesados (Fe, Cr) En Agua (9783848458806)



Los residuos de metales pesados, pueden acumularse en los microorganismos, flora y fauna acuática, y de esta manera entrar en las cadenas alimentarias humanas, dando como resultado problemas de salud tales como desordenes en la piel y daño en el hígado. En el presente trabajo se combinan dos técnicas, una convencional y una biotecnológica, la cual es una alternativa para la remoción de metales pesados, mediante un filtro que utiliza la cáscara de huevo. Se preparó una solución patrón de 1000 ppm, posteriormente se hicieron diluciones de 10, 20, 30 y 40 ppm para el Dicromato de Potasio y de 20, 30, 40 y 50 ppm para el Cloruro Férrico, cada solución con un volumen de 4 L. Se tomaron 6 muestras a diferentes concentraciones cada 10 minutos durante una hora, realizando las mediciones de la absorbancia en el espectrofotómetro UV/Vis/Nir Varian. Al realizar las pruebas se pudo observar que en el Cromo es necesario reducir el pH de 6 a 4 para que haya mayor eficiencia en la absorción, sin embargo, los resultados de absorción sólo llegaron al 18.50% para dicromato de Potasio, para el Cloruro Férrico tuvo una eficiencia del 96.29% manteniendo un pH neutro
