Resumen

RODRIGUEZ PERDOMO, Yanet  y  CURBELO HERNANDEZ, Caridad. Leaching kinetics of the red mangrove bark in water. Rev Cubana Farm [online]. 2012, vol.46, n.1, pp. 80-86. ISSN 0034-7515.

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.

Palabras clave : kinetics; activation energy; leaching; red mangrove; medicinal herbs.
