Chelating agents are substances that can bind to metal ions in a solution, forming a stable complex. This process, known as chelation, helps to remove harmful metals from the body or environment. Common examples of chelating agents include EDTA and DMSA, which are often used in medical treatments to detoxify heavy metals like lead and mercury. In addition to medical applications, chelating agents are also used in various industries, such as agriculture and water treatment. They help improve nutrient availability in fertilizers and prevent metal contamination in industrial processes. By effectively managing metal ions, chelating agents play a crucial role in promoting health and safety.
