Evaluación de la reducción del cromo total en muestras de suelos aledaños al Río Cauca por medio de un proceso químico y biológico.

Abstract

Chromium contamination in soils near the Valle del Cauca basin of the Cauca River represents a research challenge, since high concentrations of heavy metal cause social, economic and ecological problems because the proliferation of diseases that spread through the contact or by the use of it, the alteration of the economic activities of the area, and the loss of environmental quality of the soil resource due to the bioaccumulation of total chromium. Therefore, the general objective of the project was evaluate the reduction of total chromium in samples of soils near to the Valle del Cauca basin of the Cauca River, through a chemical and biological process, using nanoparticles of ferrite manganese and a symbiosis between lettuce (Lactuca sativa) and leonardite. Finally, it is concluded that the chemical method represents greater efficiency, since it obtained a percentage reduction in chromium concentration of 61.998% compared to the biological method that obtained a percentage of 8.356%.
