Synthesis of bi2O3 / CuO / Fe2O3 nanostructured semiconductors by electrochemical and hydrothermal method for the oxidation and adsorption of As3 + in water by photoelectrocatalysis.

Project: Research

Project Details


Arsenic is an element that is widely distributed throughout the environment. However, non-occupational human exposure to this element occurs mainly through water and food, which puts human health at risk, especially in rural populations. Constant exposure causes various damages associated with the development of malignant neoplasms such as cancer of the skin, cervix, stomach, etc. Another effect is a reduction in the production of red and white blood cells, which can cause fatigue, abnormal heart rhythm, damage to blood vessels, and impaired nerve function.

This research seeks to provide a solution to this problem through the use of a Bi2O3 / CuO / Fe2O3 semiconductor that will allow the decontamination of arsenic (As3 +) in water.
