Evaluación del efecto del tamaño de partícula y tiempo de contacto en la remoción de metales pesados plomo (pb) y mercurio (hg) presentes en aguas contaminadas utilizando cáscara de naranja (citrus sinensis) como absorbente natural

Abstract

The lack of effective methods to treat contamination by toxic metals from industrial and mining activity represents a severe threat to human health and ecological balance; these metals from various sources, such as contaminated soils, industrial waste and agricultural pesticides, can enter into the food chain, increasing its concentration and causing intoxication. This research aimed to evaluate the potential of orange peels as a natural absorbent material to remove heavy metals present in polluted waters. A quantitative approach and a quasi-experimental design were used to evaluate the effect of particle size and contact time on the removal of lead and mercury in contaminated water. It was found that the orange peels proved to be effective in removing these metals, establishing optimal conditions of agitation, temperature, and concentration to achieve more excellent absorption. In conclusion, the results highlighted the potential of orange peels as a biosorbent material to remove heavy metals. However, further research was needed for its largescale application and to address the removal of other toxic metals, thus contributing to protecting the environment and public health.
