  • SENSOR MEMBRANES FOR REAGENT FREE IMAGING OF DISSOLVED FERROUS IRON CONCENTRATIONS
    Publication number: 20130230928
    Abstract: A method for measuring iron concentration that includes providing a sensor including a substrate, a ferrozine containing reagent, and a polymer covalently bonding the ferrozine containing reagent on the substrate. The sensor is inserted into an iron (Fe) containing sample. The ferrozine containing reagant reacts with iron (Fe) ions in the iron (Fe) containing sample. The optical properties of the sensor are measured after the ferrozine containing reagent reacts with the iron (Fe) ions in the iron (Fe) containing sample to determine the concentration of the iron (Fe) ions in the iron (Fe) containing sample.
