Abstract
El río Moche, particularmente en su cuenca media, se utiliza para fines de riego, pero enfrenta desafíos relacionados con la contaminación debido a múltiples factores, lo que resulta en una utilización inadecuada de este recurso hídrico. Uno de sus contaminantes que con mucha frecuencia está existente en este cuerpo de agua, es el plomo; afectando al ecosistema y a las comunidades locales. El objetivo planteado es determinar la eficiencia de la cáscara de yuca en la bioadsorción de plomo presente en las aguas del río Moche, utilizando el porcentaje de remoción como medida. Para ello, se implementó una metodología que adoptó un enfoque cuantitativo, siendo un estudio transversal con un diseño experimental. En primer lugar, se recolectaron muestras in situ, las cuales fueron posteriormente llevadas al laboratorio para la preparación del bioadsorbente y la identificación de las concentraciones de plomo antes y después de la aplicación de la cáscara de yuca. Los resultados obtenidos revelaron una relación directa entre la concentración del bioadsorbente y la eficiencia en la remoción de plomo, mostrando que, a mayor concentración del mismo, la remoción es más efectiva. En conclusión, la cáscara de yuca demostró una alta eficiencia en la remoción de plomo en las aguas del río Moche, logrando alcanzar hasta un 83% de remoción en las condiciones evaluadas.
The Moche River, particularly in its middle basin, is used for irrigation purposes, but faces challenges related to contamination due to multiple factors, resulting in inadequate use of this water resource. One of the contaminants that is frequently present in this body of water is lead, affecting the ecosystem and local communities. The objective is to determine the efficiency of cassava peel in the removal of lead present in the Moche River water, using the percentage of removal as a measure. For this purpose, a methodology that adopted a quantitative approach was implemented, being a cross-sectional study with an experimental design. First, samples were collected in situ, which were subsequently taken to the laboratory for the preparation of the bioadsorbent and the identification of lead concentrations before and after the application of cassava peel. The results obtained revealed a direct relationship between the concentration of the bioadsorbent and the efficiency of lead removal, showing that the higher the concentration, the more effective the removal. In conclusion, the yucca peel showed a remarkable efficiency in the removal of lead in the Moche river water, achieving up to 83% removal under the conditions evaluated.
