Highly selective and sensitive device for detection of Mercury (II) in water

Although mercury has been used since antiquity, Earth’s mercury contamination has been widespread in the last century by human activities such as uncontrolled mining, waste incineration plants and coal combustion units. Mercury causes serious environmental and health problems. In order to increase the understanding on the deleterious effects of mercury, efforts have been made in the development of new mercury-sensing devices. With this aim and following a patented procedure, a family of molecules with metal ionic sensing capabilities have been synthesised
