Abstract
The invention generally relates to a carbon-based boron removal medium with hydroxyl group and amine group, and in particular, to a method for forming the carbon-based boron removal medium. In various embodiments, nitrogen-doped ('N-doped') graphene oxide is synthesized by a simple two-step process: (1) oxidation of graphite to graphene oxide, and (2) nitrogen-doping ('N-doping') the graphene oxide to form the amine group. The resultant N-doped graphene oxide can efficiently remove boron from aqueous solutions. The invention also generally relates to a boron sensing medium and its use in conductometric measurement techniques to detect and measure the amount of boron present in aqueous solutions.
