Arsenic and Fluoride in Groundwater, Prevalence and Alternative Removal Approach

Contamination of drinking water by arsenic and fluoride is a global problem, as more than 300 million people in 100 countries have been affected their presence. These elements are considered the most serious contaminants removal worldwide concern. Therefore, evaluation three alternative approaches—electrocoagulation, adsorption biomaterials, metal oxide magnetic nanoparticles (MNPs)—was performed for from groundwater. Arsenic synthetic groundwater (well water) was accomplished with processes; meanwhile, only reported two methods. The results indicate that an electrocoagulation process good option As (>97%) F (>90%) co-occurrence; however, operational conditions both pollutants must be driven those used removal. (80–83%) biomaterials also successful, even when application objective Finally, MNPs (Co Mn) were designed applied reached >95%. Factors such pH, presence interfering ions, initial concentration decisive treatment process’s efficiency.
