Red mud is a bauxite industrial waste of reddish-brown with high alkalinity. has relatively silica and alumina content, so it can be utilized as raw material in the synthesis zeolite. This study aims to synthesize high-purity NaP zeolite from red at various SiO2/Al2O3 mole ratios. The begins neutralizing mud, followed by decomposition using alkaline fusion method ratio mud:NaOH = 1:1 (w/w). fil...
