Abstract:The response surface methodology (RSM) is applied for predictive estimation and optimization of
decolourization of safranine, a phenazine dye by a chemical oxidation process using iron(II) as
homogeneous catalyst and chloramine B (CAB) as an oxidant in acid medium. All experiments were
based on the statistical designs in order to develop the predictive regression models and for optimization.
Four independent variables (temperature, catalyst, CAB and acid concentration) were chosen to optimize
the decolourizati… 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.
