Application of Taguchi method and response surface methodology into the removal of malachite green and auramine-O by NaX nanozeolites

Abstract In the present study, the simultaneous removal of malachite green (MG) and auramine-O (AO) dyes from the aqueous solution by NaX nanozeolites in a batch system is investigated. Taguchi method and response surface methodology (RSM) were used to optimize and model dye removal conditions. In o...
