A method has been developed for the determination of traces of boron in graphite powder. The graphite powder was made into a paste using Na 2 CO 3 solution (flux). The paste form of graphite powder was fused in a muffle furnace and was mixed in a glycerol solution. The flux was separated from the glycerol solution as a solid residue by heating over a water bath. The boron present in the glycerol solution was measured by ICP-OES. Compared to conventional Na 2 CO 3 fusion, the amount of flux and fusion time were reduced by a factor of 32 and 8, respectively. Due to the extraction of boron from the flux into glycerol solution, the preconcentration was increased by a factor of 200. The separation of flux was >92% with the recovery of analyte in the range of 92-96%. The detection limit was found to be 90 ng g À1 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
