Abstract: La presente investigación tuvo como propósito, evaluar la influencia del tiempo de contacto y el pH para la biosorción de zinc en el río Grande – Quiruvilca, iniciando la investigación en una concentración inicial de 238,48 mg/L de zinc; para ello se utilizó tratamiento usando cáscaras de granadilla (Passiflora ligularis L.), que por su característica adsorben altas concentraciones de contaminantes. El diseño que se adaptó en la investigación fue factorial, la muestra fue de 4 litros de agua contaminada, distribuida en vasos de precipitación de 250 mL cada una a diferentes pH de 6, 8 y 10; en tiempos de 4, 8, 12, 16, 20 y 24 minutos. Las muestras de agua contaminada con zinc fueron analizadas en el laboratorio de análisis instrumental de la carrera de Ingeniería Ambiental en la Universidad Privada del Norte, para lo que se utilizó el equipo el espectrofotómetro de absorción atómica tipo llama; el método de procesamiento de análisis de datos fue el ANOVA, para determinar el efecto de la relación entre variables independientes en la dependiente. Finalmente se afirmó la hipótesis que el pH y el tiempo influyen en la adsorción de Zinc; mostrando la relación óptima a un pH de 10 en un tiempo de 24 minutos con una adsorción de 0,09 mg/L de zinc con un 99.96%. Los datos de equilibrio se ajustan mejor a la isoterma de Langmuir con una adsorción máximo de 93.4579 mg/g de zinc además la cinética del proceso de biosorción de Zn se adecúa a un modelo de pseudo segundo orden.
The purpose of this research was to evaluate the influence of contact time and pH for biosorption of zinc in the Rio Grande - Quiruvilca, initiating the investigation in an initial concentration of 238.48 mg / L of zinc; for this treatment was used using granadilla peel (Passiflora ligularis L.), which due to its characteristic adsorb high concentrations of contaminants. The design that was adapted in the investigation was factorial, the sample was 4 liters of contaminated water, distributed in precipitation glasses of 250 mL each one at different pH of 6, 8 and 10; in times of 4, 8, 12, 16, 20 and 24 minutes. Samples of water contaminated with zinc were analyzed in the instrumental analysis laboratory of the Environmental Engineering career at the Universidad Privada del Norte, for which the flame-type atomic absorption spectrophotometer was used; the data analysis processing method was the ANOVA, to determine the effect of the relationship between independent variables in the dependent one. Finally, the hypothesis that pH and time influence Zinc adsorption was affirmed; showing the optimum ratio at a pH of 10 in a time of 24 minutes with an adsorption of 0.09 mg / L of zinc with 99.96%. The equilibrium data are better adjusted to the Langmuir isotherm with a maximum adsorption of 93.4579 mg / g of zinc, and the kinetics of the Zn biosorption process is adapted to a pseudo-second order model.
