Determinación de la eficiencia de bioadsorción del colorante rojo allura #40, utilizando tusa de maíz, cáscara de banano y cascarilla de arroz; aplicado a aguas sintéticas

Abstract

The presence of dyes in the aqueous effluents generates a negative impact on the environment, drastically affecting the aesthetics and self-regeneration of the water resource. As a result, multiple technologies have been used in order to reduce the impact of dyes on effluents, including bioadsorption, which emerges as an alternative to not only mitigate this impact, but reduce the costs of conventional treatments, using as an adsorbent material organic material of vegetable origin, as is the case of the corn gourd, banana peel and rice husk, which have been used for the present work, in which the bioadsorption efficiency of the red colorant is determined # 40 applied to synthetic waters, which took into account variables such as pH, adsorbent material and particle size, and constants such as ambient temperature, contact time and dye concentration, obtaining a removal efficiency of 99.911% for the gopher corn, 99,366% for banana peel and finally the rice husk 86,560% in batch test. Finally, for a column test where the optimal conditions of the batch test of the corn gop were replicated, a removal percentage of 99,657% was obtained, demonstrating that the use of agricultural material is an alternative for the adsorption of dyes.
