Abstract

The objective of this research was to create methods that are efficient and economical for eliminating fluoride from groundwater. Water, which is the most essential element for maintaining life on our planet, has been seeing a gradual decline in quality as a result of India's growing population, increasing industrialisation, and increasing use of pesticides in agricultural practices. Fluoride ions, which may be found in both groundwater and surface water, are the most significant contributor to water deformation. As a result of studying the study, it was shown that fluoride is the most prevalent problem all over the world. As a result, we devised a novel method for removing fluoride concentrations from groundwater by using cow urine, nanoparticles of cooper oxide, and active charcoal that was made from Thespesia populnea. This approach resulted in a reduction in fluoride content by fifty percent, and it has also been published by the Indian Patent Office under the number 202311051829A, which is the patent application number for this technology.
