Abstract:The Fe in graphene was determined by inductively coupled plasma optical emission spectroscopy. The effects of digestion temperature, digestion system, analyzing spectral line, RF power, peristaltic pump flow rate, and working gas flow rate on the measurement results were investigated respectively. The results show that the best digestion effect appear when the digestion temperature is 550 °C and the digestion system is 3ml hydrochloric acid combined with 1ml nitric acid. The most stable and reliable test resul… Show more
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.
