Implementación de una Técnica para el Aprovechamiento de los Alcaloides de Chocho y Posterior Complexión de Metales Pesados

Abstract

In the present study, the appropriate conditions to form complexes with the alkaloids of Chocho desamargado and heavy metals present in wastewater were determined. Standard solutions of heavy metals and chocho debittered water with different alkaloid concentrations were used, in addition to volumetric, potentiometric and spectrophotometric techniques to obtain data and construct multifactorial experimental designs for Cadmium, Lead and Chromium, used in this project. The results obtained indicate that at a concentration of 4.59 mg/ml of alkaloid and pH 4, Cadmium precipitates; at a concentration of 1.24 mg/ml of alkaloid and pH between 3 and 4.5, Lead precipitates; and at a concentration of 4.59 mg/ml of alkaloid and pH 8, Chromium precipitates, reducing the levels of Chromium, Cadmium and Lead by 76, 85 and 91 % respectively. The conditions obtained are applied to a sample of oil formation water, reducing Lead by 17%, demonstrating that the alkaloids precipitate heavy metals, in addition to the fact that there are interferences that hinder the treatment of metals in the formation water sample. The results obtained can serve as a basis for the development of projects for the removal of heavy metals from water contaminated by them, coming from the industrial, mining or hydrocarbon sectors, with the design and construction of treatment plants for this type of effluents.
