Iron is the fourth abundant element on Earth’s crust and it is present in various rock and soil minerals in the form of iron (II) and iron (III). Iron is a crucial element for both plants and animals since it plays an important role in several metabolic processes. Iron and its compounds interfere with natural sources as a pollutant through the discharge of wastes since they have been widely used as containers and pipelines all over the world. Consequently, it became important to detect and monitor iron levels selectively and sensitively for not only in biological samples but also in industrial and environmental samples. Potentiometric sensors have been developed by immobilizing a membrane matrix on all-solid-state contact. This technique has advantages such as sample monitoring without any reagent consumption and very short analysis time. The all-solid-state contact sensor was prepared in certain ratio of graphite-epoxy resin and then the surface of all-solid-state contact sensor was coated with the sensing membrane without an internal reference solution. Therefore, its potentiometric response became more stable and life-time of the sensor increased without any loss in its potentiometric characteristics. To the best of our knowledge, there is no report available in literature regarding the detection of Fe (II) using dithiocarbamate as a sensing material. In this study, a novel iron(II) ion selective sensor was developed and the electrode composition was optimized
