Cinética de lixiviación de la corteza de mangle rojo en agua

objective: to determine the type of phenomenon ruling the mass transfer during leaching of red mangrove in water by studying the kinetics of this process. methods: the kinetics of leaching of red mangrove bark into water at lab was studied in a solid/liquid ratio of 1:4 at different temperatures (25, 45, 70 and 90 oc). for each temperature, the kinetic constant was estimated from the fundamental leaching equation by a fitted model using the statistical program curveexpert 1.4 for windows. results: the total soluble solid concentration values showed a sizeable increase at 25 and 45 °c in the first 20 minutes and at 70 and 90 °c in 30 minutes. the activation energy in the experiment amounted to 2.884 kj. conclusions: the leaching of the red mangrove bark is of physical origin.
