Biodegradable chelating agents are eco-friendly compounds designed to bind and remove metal ions without lingering in the environment. Unlike traditional chelating agents such as Ethylenediaminetetraacetic Acid (EDTA), biodegradable agents like Methylglycinediacetic Acid (MGDA), Glutamic Acid Diacetic Acid (GLDA), and Ethylenediamine-N,N-disuccinic Acid (EDDS) naturally decompose through microbial activity, thereby minimizing ecological impact. These agents are extensively utilized in various applications, including detergents, water treatment, agriculture, and personal care products, providing an effective and sustainable solution for metal ion control.
