Abstract

The objective of the investigation was to determine adsorption of lead and iron in waters coming from the Santa River, Recuay jurisdiction, Ancash. Then the synthesis of titanium dioxide nanoparticles (TiO2) was carried out by means of ultrasound, and finally the adsorption of the metal ions present in these waters by means of the titanium dioxide nanoparticles. The results indicate that the iron was adsorbed by 92.69% (from 31.86 mg/L to 2.33 mg/L) and the lead was adsorbed by 79.58% (from 2.361 mg/L to 0.482 mg/L) using 600mg of titanium dioxide nanoparticles (TiO2) and a treatment time of 60 minutes of treatment.

Highlights

Water is a fundamental natural resource for the development of life on the planet, since it constitutes an indispensable factor for the development of biological processes (ANA, 2016)
The main metallic ion that pollutes the waters of the Santa River, in the section adjacent to the mining environmental liability Ticapampa is lead (Pb), this metal can accumulate in living organisms in a way that achieves higher concentrations, being this dangerous for the health by presenting a high level of toxicity; manganese (Mn) and iron (Fe) exceed the environmental quality standards for water in the Santa River, the presence of iron in the water causes precipitation and unwanted coloration, while manganese can cause poisoning in mammals at high concentrations (Vera and Rosas, 2017)
Lead and iron were adsorbed in waters coming from the Santa River by applying titanium dioxide nanoparticles

Summary

Introduction

Water is a fundamental natural resource for the development of life on the planet, since it constitutes an indispensable factor for the development of biological processes (ANA, 2016). The main metallic ion that pollutes the waters of the Santa River, in the section adjacent to the mining environmental liability Ticapampa is lead (Pb), this metal can accumulate in living organisms in a way that achieves higher concentrations, being this dangerous for the health by presenting a high level of toxicity; manganese (Mn) and iron (Fe) exceed the environmental quality standards for water in the Santa River, the presence of iron in the water causes precipitation and unwanted coloration, while manganese can cause poisoning in mammals at high concentrations (Vera and Rosas, 2017). The present investigation applied nanoparticles of titanium dioxide (TiO2) to achieve the adsorption of metallic ions; with the purpose of decontaminating the waters of the Santa River and meeting the environmental quality standards for water required by the Ministry of the Environment
