Abstract
La contaminación del agua por presencia de metales pesados como el plomo, es un problema mundial que ha desequilibrado el sistema de salud en la humanidad, toda vez que este metal afecta la pureza del agua bebible, poniendo en peligro la sobrevivencia de los seres vivos, ya que el plomo afecta los sistemas nervioso, hematológico, cardiovascular y reproductivo; frente a ello, la biosorción, se presenta como un efectivo método alternativo, motivo por el cual el presente estudio tiene el objetivo de dar una visión general y actualizada sobre la capacidad biosortiva del Nostoc commune en la eliminación de plomo de aguas contaminadas. Se realizó la revisión y análisis del estado del arte en sus fases heurística y hermenéutica acerca de la capacidad biosortiva del Nostoc commune, recopilando artículos científicos y tesis relacionados a la biosorción del plomo utilizando descriptores como "biosorción", "quimiosorción", "Nostoc commune" "metales pesados". Se resalta que la capacidad biosortiva está comprendida entre 247,35 y 384,62 mg pb / g de Nostoc commune; y el modelo que describe fue Langmuir (R2) comprendido entre 98,8 y 99,25%; siendo el Nostoc commune un potencial biosorbente altamente eficiente para separar el plomo de aguas contaminadas, a través de grupos carboxilos e hidroxilos, azúcares reductores, saponinas y aminoácidos, concluyendo que, el Nostoc commune tiene alto potencial biosorbente y muy efectivo para contrarrestar la presencia de plomo en el agua.
The contamination of water by the presence of heavy metals such as lead is a global problem that has unbalanced the health system of mankind, since this metal affects the purity of drinking water, endangering the survival of living beings, since lead affects the nervous, hematological, cardiovascular and reproductive systems; In view of this, biosorption is presented as an effective alternative method, which is why this study aims to provide an updated overview of the biosorptive capacity of Nostoc commune in the elimination of lead from contaminated water. A review and analysis of the state of the art in its heuristic and hermeneutic phases was carried out on the biosorptive capacity of Nostoc commune, compiling scientific articles and theses related to lead biosorption using descriptors such as "biosorption", "chemosorption", "Nostoc commune" and "heavy metals". It is highlighted that the biosorptive capacity is comprised between 247.35 and 384.62 mg pb / g of Nostoc commune; and the model describing was Langmuir (R2) comprised between 98.8 and 99.25%; being Nostoc commune a highly efficient biosorbent potential to separate lead from contaminated water, through carboxyl and hydroxyl groups, reducing sugars, saponins and amino acids, concluding that, Nostoc commune has high biosorbent potential and very effective to counteract the presence of lead in water.
