The degradation of the dye was studied by UV-Vis spectrophotometry, for two concentrations of strontium aluminate powder and five of the dye for one hour. The chemical composition and morphology of strontium aluminate powders was studied using X-ray scattered energy spectroscopy, X-ray fluorescence and scanning electron microscopy. The pH, total dissolved solids, and electrical conductivity of the water samples before and after treatment were measured using the Handy-Lab 680 multiparameter. It is evident in the morphology of the strontium aluminate powders a synthesis by reaction in solid state, and a chemical composition by weight of strontium oxide and small amounts of europium and dysprosium. The photocatalytic treatment reports an efficiency of 100% in the removal of the dye for the strontium aluminate powder concentration of 500 mg/L, while for 1000 mg/L an efficiency of 98% was found, likewise for a concentration of 60 mg/L and one hour of ultraviolet radiation a first order reaction kinetics in the degradation of the dye was evidenced.
