Chalcogels preferentially absorb heavy metals, showing promise in absorbing pollutants mercury, lead, and cadmium from water. In addition, scientists have made one that is claimed to be twice as effective at desulfurization as any current methods. This is a very impressive feat, particularly because until the discovery of chalcogels' properties, scientists were beginning to consider desulfurization an optimized process.
