Abstract
El propósito de la investigación consistió en evaluar el impacto del tamaño de
partícula y el tiempo de tratamiento de la cáscara de Musa Sapientum en el proceso de
remoción de metales pesados, el objetivo fue disminuir concentraciones de Pb y Zn, de
un efluente de flotación.
Se realizaron 27 pruebas experimentales, implantándose un diseño experimental
de modelo 22 y 3 repeticiones, considerando el tamaño de partícula de la cáscara de Musa
Sapientum y el tiempo de tratamiento como factores influyentes, y los porcentajes de
remoción de Pb y Zn como variables de respuesta. En base a esta investigación, en la cual
se trabajó con tamaños de partícula de 100 % - m#10, 100 % - m#30 y 100 % - m#50, y
tiempos de tratamiento de 10 min, 30min y 60 min; se pudo concluir que la mejor
eficiencia de remoción de Pb y Zn, se logra con partículas de 100 % - m#50 y una duración
de tratamiento de 60 min, obteniendo porcentajes de remoción de 55,1 % Pb y 30,8 % Zn.
The purpose of the research was to evaluate the impact of particle size and treatment time of the Musa Sapientum shell on the heavy metal removal process; the objective was to reduce concentrations of Pb and Zn from a flotation effluent. 27 experimental tests were carried out, implementing an experimental design of model 22 and 3 repetitions, considering the particle size of the Musa Sapientum shell and the treatment time as influential factors, and the removal percentages of Pb and Zn as response variables. Based on this research, in which we worked with particle sizes of 100% - m#10, 100% - m#30 and 100% - m#50, and treatment times of 10 min, 30min and 60 min; It was concluded that the best removal efficiency of Pb and Zn is achieved with particles of 100% - m#50 and a treatment duration of 60 min, obtaining removal percentages of 55,1 % Pb and 30,8 % Zn.
