Modelagem da remoção de azul de metileno por carvão ativado de borra de café em micro coluna de leito fixo

Abstract

The use of waste in the production of soluble coffee for effluent treatment has become a focus of interest to many engineers and environmentalists around the world. However, electric shock was produced from breakfast as one of the major components of methylene liquid. The adsorption experiments were performed at 293.15 free of diameter and 10 mm in diameter, with flow rates of 1.0, 0.9, 0.8, 0.7 and 0.6 mL min-1 and using a Statistical technique ANOVA of a factor to verify the flow performance. A mathematical model was proposed by Thomas, Yoon-Nelson and Adams-Bohart for the performance and adsorption capacity of the column. The experiments to understand how the molecular interactions of the column originate from the construction of the isotherm. The isotherm curve was constructed by varying the concentration between 10, 20, 30, 40 and 50 mg L-1, keeping 0.8 mL min-1 fixed, 293.15K fixed temperature. The following were modified as the temperature ranging from 293.15 298.15, 303.15, 308.15 and 313.15 K ex. 0.8 ml min-1, microcarrier dimensions 2.0 x 10 mm and concentration of 30 mg L-1. The data were tested using a Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Hill, Redlich-Peterson and Sips modeling. For the kinetic mechanism survey, the data collected for the flow test were used and as the modeling was used pseudo-second order and intraparticle.
