Determinación de la capacidad filtradora de CR y PB de la VALVA pulverizada de Anadara Tuberculosa mediante muestras líquidas adyacentes a la zona habitada en la Isla Santay, Guayaquil, Ecuador

Abstract

In this research, experimental and correlational methodology was used to identify heavy metals (Cr and Pb) present in liquid samples obtained in areas adjacent to Santay Island. A laboratory-scale treatment was implemented in order to determine the removal efficiency of heavy metals (Cr and Pb) using the pulverised shell of Anadara tuberculosa in water samples with metal concentrations (Pb and Cr) of 10.83 and 15.63 ppm. The analysis of physicochemical parameters and heavy metals was carried out using multi-parameter equipment, potentiometer and inductively coupled plasma atomic emission spectroscope (ICP-OES) from the laboratories of the Salesian Polytechnic University - Guayaquil. In conclusión, as results of the experiment, 96 and 99% Pb removal values were obtained at pH 7 and 10, respectively. Similarly, 53 and 76% Cr removal values were obtained at pH levels 7 and 10.
