Abstract:This study aims at developing an analytical procedure capable of quantifying the ferric oxide present in the mixture of ferric oxide/lactose monohydrate (0.4% w/w). The analytical procedure was checked for specificity, linearity, precision (system repeatability, procedure repeatability and intermediate precision), accuracy, stability of solutions and robustness of the procedure. The concentration of Fe (III) was determined by spectrophotometry at 480 nm based on calibration curves. The specificity was verified… 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.
