Abstract

With industrial development and the increase of human activities, the content of fluoride ions in water bodies is constantly rising, resulting in serious human health risks and environmental ecological pollution. Traditional methods for removing fluoride ions are usually costly and energy-intensive, making it difficult to apply them on a large scale. Therefore, finding low-cost, efficient, and environmentally friendly methods for removing fluoride ions has become one of the research focuses of various countries. However, due to their wide range of sources, low prices, and some unique pore structures and surface chemical properties, solid wastes can effectively adsorb fluoride ions. In order to explore the ability of solid waste to remove fluoride ions from water, this paper concludes that modified solid waste has a high fluoride ion removal rate under certain conditions, and also exhibits good reusability and stability. This paper not only provides a new way of thinking for the treatment of fluoride ion pollution but also achieves the secondary use of solid waste resources, which has good environmental and economic benefits.
